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.
- 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!
- Super cool magnet Review by Robin
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! (Posted on 5/31/13)
- bad expreince Review by may
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

- A perfect magnet for all around use! Review by Gregory Willison
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. (Posted on 5/31/13)

It is great!!! (Posted on 5/31/13)
- Great powerful Magnet Review by Claudia Garcia delPuerto
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. (Posted on 5/31/13)

Very strong and my son loved it. (Posted on 5/31/13)
- Magnet Review by Jared H.
We bought 2 of your neodymium magnets and one chiped a large chunk off.
But's it's a great magnet (Posted on 5/31/13)
- Wow! This little magnet packs a powerful punch Review by ScienceMom
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) (Posted on 5/31/13)

- careful Review by Kevin
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.(Posted on 5/31/13)
- is fun but... Review by jlee
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.

- Love It All Review by Sage
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 (Posted on 5/31/13)
- STRONG Review by Karen Baker
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. (Posted on 5/31/13)

that is a powerful magnet!
not as big as I imagined (I know you had the size listed, but I had a preconceived idea) (Posted on 5/31/13)
- COOL MAGNET Review by Vicki
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. (Posted on 5/31/13)
- Very Impressive Review by Patrick Rusca
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!

- keep away from credit cards Review by Jessie Sapp
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. (Posted on 5/31/13)

this thing is cool and awsome. (Posted on 5/31/13)
- very strong! Review by nancy faris
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. (Posted on 5/31/13)
- MEGA MAGNET Review by Julie
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. (Posted on 5/31/13)
- Good clean fun Review by B Czyryca
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 (Posted on 5/31/13)
- 3rd grade science experiment Review by Darcy Schoenberg
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! (Posted on 5/31/13)
- Not so great Review by Monica Shadid
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. (Posted on 5/31/13)
- Great magnets! Review by Susan A
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. (Posted on 5/31/13)
- middle school fun Review by Theodore
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. (Posted on 5/31/13)
