Neodymium Magnet

Quick Overview

The strongest magnets in the world!


Availability: In stock


Hey, these magnets are strong! Stick one in your pocket and accidentally walk by the refrigerator, and your family will find you stuck to the door! Just one of these magnets will hold a small phone book to a steel filing cabinet (the things we do when we're bored!). They can even detect traces of iron in an ordinary $1 bill. We need to remind you to keep these magnets away from your credit cards, computer disks, videotapes, small children and anything else of value. Recommended for children ages 8 and up.

Find Meteorites! You can use these super-strong magnets to find micrometeorites hiding in your drain spouts.

Note: Picture demonstration possible with two magnets.

What's Included?

  • One super-strong neodymium magnet measuring 2 cm X 3 cm X 1.25 cm
    • Grade 35 with approximately 40 pounds of pull.

How Does It Work?

Neodymium magnets also contain Iron and Boron, making them some of the strongest magnets in the world. Magnets of all types create a magnetic field, with both a north and south pole. The magnetic field created by the neodymium magnets is so strong, it will line up to match the magnetic north and south of the earth. It makes a great compass! On a more serious note, the large magnets are so strong that they may even be dangerous if not handled properly. A pair of these magnets will leap into a deadly embrace from over 6 inches apart and may knock chips off themselves from the force of the impact. You’ll be amazed at the super strength of the magnets, but we must warn you to be careful. Any type of magnetic media will be history in the presence of one of these large neodymium magnets.

What Does It Teach?

Discover the magic of magnetic fields, friction, and the magnetic poles of the earth. U.S. dollar bills are printed with magnetic inks so that their passage from hand to hand can be traced. They are designed to prevent counterfeiting. Get a dollar and fold it in half. Hold the neodymium magnet near the bottom of the bill and notice how it attracts the iron. This could be a great magnetic demonstration for a science fair!

  1. So much fun review by Cindy on 1/4/2014

    These are great.....but like other reviews there are drawbacks. My grandsons hadn't played with them very long before they chipped. They are so strong, if placed very close together, they will attract fairly violently causing them to chip.

  2. Wow! This little magnet packs a powerful punch review by ScienceMom on 5/1/2013

    We used this for my daughter's science experiment -- "Is Your Breakfast Magnetic?" -- and did the experiment to see if any iron particles come to the surface from cereal soaked in water inside a baggie. This magnet produced great results. We had initially purchased a magnet from the hardware store, but the strength of it was weak. Then the Spangler website ran this magnet as the Deal of the Day, so we ordered it. It came in quickly, and really made a positive difference in showing iron particles in cereal. Much better than the magnet from the hardware store. (don't leave this magnet attached to other magnets. My daughter left it attached to the magnet we bought from the hardware store for a couple days, and it began to degrade the hardware store magnet -- small particles started coming off that magnet and sticking to this magnet)

  3. Magnet review by Jared H. on 4/9/2013

    We bought 2 of your neodymium magnets and one chiped a large chunk off.
    But's it's a great magnet

  4. great magnet review by Dr T Redling on 2/27/2013

    Very strong and my son loved it.

  5. Great powerful Magnet review by Claudia Garcia delPuerto on 2/19/2013

    I bought it for my daughters science project (finding if cereal has iron in it). It worked very well. It's is very strong and you can study and experiment how magnets work. I recommend it.

  6. Great review by Maria Liza on 1/10/2013

    It is great!!!

  7. A perfect magnet for all around use! review by Gregory Willison on 12/6/2012

    I am a magician and this magnet is the perfect size and has enough power to do many interesting demonstrations. I keep mine in a soft carrying case, so there is no chance of it getting damaged. If you are thinking of doing any demonstration that requires a very strong, medium sized magnet this is for you.

  8. bad expreince review by may on 10/16/2012

    i tried one of these magnet out when i first got it. Shocking to say it had split it half within minutes of playing with it

    I would like a replacement because i have ordered many times from this site and have been completely happy with my order but this time i felt like i wasted my money

    We don't like that at all! One of our customer service representatives will be contacting you soon regarding your broken magnet. We want to make sure you have a good experience!

  9. Super cool magnet review by Robin on 9/11/2012

    Love this super cool magnet! Sent it to school with my daughter along with a box of total cereal, a dollar bill, paper clips, and dirt/small rocks from gutter.....they are still having fun with it!

  10. middle school fun review by Theodore on 7/24/2012

    I was in my class when she brought them out, we had pairs of 2's because we didn't want them to get to close to each other. We had a lot of fun with them,we had bottles of sand and iron ojects using the magnet to move the iron around.It would've been cool if you could've came but we just finished with the lesson. I think it would be cool if you could come before christmas break to wrap up the lesson. Anyways the magnets are a blast of fun for everyone.

  11. Great magnets! review by Susan A on 6/1/2012

    I run a science club at my school and we've used these for several years. The kids LOVE them, especially puttin the magnet on top side of their hand and holding the paperclips up on the bottom side. The down side was one ended up on the back of my computer tower... hmmmm... not so good. Loved the magnets... will use them over and over.

  12. Not so great review by Monica Shadid on 4/22/2012

    The magnet didn't really work like I was hoping it would. When placed on top of the hand, I wanted kids to be able to pick up paper clips and nothing stuck. It's a strong magnet, just not strong enough for what I was wanting.

  13. 3rd grade science experiment review by Darcy Schoenberg on 2/24/2012

    My daughter performed the "eating nails for breakfast" experiment for her class and received rave reviews from her teacher and classmates alike. I just wish my husband would take the warnings as to how powerful the magnet is as seriously as my 9 year old!

  14. Good clean fun review by B Czyryca on 1/27/2012

    The paper clip thing did not work for me, even though I have a skinny hand. So it definitely didn't work with my high school boys. But they have a ball playing with it before class and rush to volunteer to clean up the magnetic bingo chips using this magnet. But it is hard to get the chips off the magnet! Oh yeah, great price. Thanks

  15. MEGA MAGNET review by Julie on 1/13/2012

    I gave my nephew a Mad Science birthday party. I purchased two of these magnets to use as one of the experiments. We had a paper plate full of paper clips, placed the magnet over the back of the kids' hand and they were able to pick up the paper clips. They thought this was cool. Be warned...the magnets are VERY STRONG!!! I hope to use these one day for a science project with my son.

  16. very strong! review by nancy faris on 11/15/2011

    This magnet could do anything you need a strong magnet for. It is truly amazing! It is very good for teaching Earth Science and Physics.

  17. awsome review by Debbie on 11/6/2011

    this thing is cool and awsome.

  18. keep away from credit cards review by Jessie Sapp on 10/27/2011

    Read the warnings. This is a very strong magnet and will erase credit, debit, and other cards with magnetic strip on back from a few feet away. I am in the process of reordering all new credit cards because I carried the package in with my purse in hand. Works great for the "nails for breakfast" experiment.

  19. Very Impressive review by Patrick Rusca on 10/1/2011

    The power in these magnets blew me away. I bought nine for a classroom activity, but may have to rethink it. They are simply too strong, too magnetic! These things attract to each other with such force that one of them chipped the other one. (yes I saw the warning, but only after this chip had occurred.) Additionally, my colleague had his skin caught between the two during a collision and he formed a blister on his hand. How can I let kids play with this? Yeah, not going to happen. But I could do a demo, with me and only me doing the manipulation. That's a compromise on the danger factor.

    Overall I'd say the magnets are awesome... perhaps too awesome? Are there websites or links that people have using these impressive magnets in classroom safe ways? I'd love to get a list of fun things to do!

  20. COOL MAGNET review by Vicki on 8/17/2011

    This is a magnet that will really show what magnetism can do and it's not that much money. I use mine a lot but watch out cause it really is strong. Fun to demonstrate with in the classroom since it can pick up paperclips through your hand. Any science teacher would love this thing.

  21. Neo d magnet review by geoff yamamoto on 8/5/2011

    that is a powerful magnet!
    not as big as I imagined (I know you had the size listed, but I had a preconceived idea)

  22. STRONG review by Karen Baker on 7/6/2011

    This magnet is very strong! The students were enjoying just testing it's strength (as well as their own). I bought it in order to have my kids separate the iron out of their cereal. It worked wonderfully! I would recommend these magnets to any teacher looking for a strong magnet.

  23. Love It All review by Sage on 6/7/2011

    Hi, I bought a neodymium magnet from your online shop and it is AMAZING!!!!! and ever since i saw one of your videos, its all I watch, and also, when you make an appearance at a school, how do you choose which school you go to, because I think that it would be REALLY cool to have you come to my school, I LOVE ALL YOUR VIDEOS! :P

  24. is fun but... review by jlee on 4/12/2011

    i bought two for my daughter's Mad Science party to do the paper clip trick but somehow the second magnet cracked in half and was split w/ sharp edges so it had to be thrown away. the girls had fun w/ the one left tho. you should be careful when handling this magnet...very strong.

  25. careful review by Kevin on 3/5/2011

    If you buy 2 magnets they will probably shatter after the first few impacts. These are very strong, even in the hands of adults. They are brittle.

  26. magnet review by amendiola on 1/10/2011
