Arrange these compasses around magnets and the compass needles will align with the magnetic field. Not to be used for hiking.

One Star Half of them did not work at all. Well it is very inexpensive so I guess cheaply made
Toy A little small than expected & not very accurateBut it’s a cheapy toy that the kids had fun playing with
Price is indicative of quality They served their purposed for me which was a small electromagnetism demo for a girl scout event. I think out of the whole batch we only had one that was completely useless. They are very small, roughly between a nickel and quarter. I like the idea of the one of the other reviews to used them as buttons they are about the right size for that.
