If you need bar shaped magnets with greater holding or repelling force, see: neodymium magnet blocks.
Watch this video of the magnaprobe in action that shows how to identify a magnetic field around a bar magnet.
Two 100x20x7mm bar magnets were placed in contact with opposing poles (N:N). They were released and the distance caused by the repulsive force was measured.

Great magnets! I ordered a bunch for my classroom, they arrived quickly and have held up nicely. Great product and service, I would definitely order from indigo again.
