These look like regular marbles, but they're also magnets! Build all kinds of pyramids, walls, and geometric designs or just play marble games. Use your imagination, they're great for science projects! Recommended for ages 6 and up.
Available in packages of 20 or 400 magnetic marbles.
How does it work?Inside each tiny marble is a cylinder-shaped magnet, giving the marbles a north and south pole.
What does it teach?
Encourage creativity and exploration in your students. Learn about magnetism, geometric shapes, color matching and patterning.
Hold a marble in your hand and see how many marbles you can pick up without breaking the chain. To find out the actual magnetic force between the top two marbles, weigh the marble chain minus one marble.
What is the diameter of the marbles?
Each of the marbles has a diameter of 17.5mm (11/16 in).

The magnetism is not quite as strong as I would like to see and seem to be off balance inside (not evenly distributed) my kids however, love them regardless.

While they were marbles (plastic) and magnetic, the magnetic field was very weak. You could hardly pick a couple of marbles up at the same time. If the magnetism was stronger I would give these a 5 stars, but due to the very disappointing weakness of the magnet I can only give it one star.

I bought these for my entire daycare for christmas (except the wee ones). We had been working on attraction/repulsion and everyone old enough loves magnets. These were bright colored as well and within my budget for the entire daycare. I was very excited about receiving these and thought I had nailed it for this years gift...until I opened a bag to check them out. They are colorful but hardly even magnetic. Your lucky if it picks up one other marble. If you roll them by the others with any momentum, they won't even disturb the others they cruise by. They were very disappointing and not fun to "experiment" with at all. Spend your money elsewhere.
Marbles yes but magnets no

I recently purchased these magnetic marbles for a class I was teaching and was sadly disappointed with there lack of magnetic attraction. They are able to only stay connected to each other if they are lying on a table and even then they come apart very easily. I would not recommend anyone buy these and would recommend Steve Spangler Science find some other magnetic marbles to offer. These are a poor product.

The magnets aren't really stong enough to be very good for building as advertised.
