3 Inch Educational Alnico Bar Magnet with North South Identified for Student Teachers Science Education, 2 Pack

These magnets are very well-made. Strong enough for my demonstration of repel and attract. My grandson the letter identifying North and South are big. Definitely, the value of the product is great!

Doesnt attract and repel hardly at all, I have more magnetic force in the closure on my iPad cover. Go with something else and if you find it let me know. I didn't expect much for the price. Still looking for some good magnets to teach school with.

A little brittle but worked well for my class.

Teaching Great Grandchildren About Magnetic Forces

Pictures in the product page implies the magnet bars are much larger. They're actually a size you would expect in a prize in a Christmas cracker. Something you would buy at a dollar store.

These are really powerful and perfect for science projects.

These worked great for our science experiment using magnets! Great quality!

These work fine for demonstrating magnetism and polarity, but the paint and lettering on mine were extremely sloppy. Your mileage may vary.
