Frequently Asked Questions (FAQs)

1. What is a block magnet?

Block magnets are six-sided magnet with straight sides where all angles are right angles (90°). Opposite sides of the magnet are parallel. They are commonly used in holding applications where they fit within a channel to increase their holding force.

2. What can deactivate a magnet?

Demagnetize a Magnet by Heating or Hammering If you heat a magnet past the temperature called the Curie point, the energy will free the magnetic dipoles from their ordered orientation. The long-range order is destroyed and the material will have little to no magnetization.

3. What are the strongest commercial magnets?

Neodymium magnets, or rare earth magnets, are known to be the most powerful type of permanent magnets available to consumers today.

4. How do you disable a permanent magnet?

Touch the bottom of the magnet to a steel surface that you want it to stick to, and turn the knob. Now it attracts with an incredibly strong force. We're talking about the surprisingly strong neodymium magnet kind of force! When you want to remove it, simply turn the knob back to the OFF position.
