Supertek® Steel Bar Magnet

Simple magnets for physics labs,

• Large magnet is 20 cm in length

• 19×6 mm cross-section

Steel is the simplest material for permanent magnets as well as the most economical. These magnets aren't the strongest ones you've ever used, but they are physically robust (they won't break like a ceramic magnet) and can be ‘recharged’ using a remagnetizer.
