Review on Magnetic Marble Diameter by Ajax Scientific: Unleash the Power of Attraction by Trey Tucker

This product is the best! As a result of my tests, I determined that it has amazing magnetic strength that makes it easy to demonstrate the properties of magnetism. The size is perfect for students to handle and observe the behavior of the marbles. The only downside is that it may be too small for large group demonstrations. Overall, this is an excellent tool for anyone teaching magnetism.
