How to Build an ON/OFF Switch for a Permanent Magnet
Ever wanted to build a magnetic switch for a permanent magnet?
Watch and see how a magnetic switch can be built in a few simple steps. The switch is built with 3 equal magnets and iron bars.
It is obviously not possible to turn off the magnetic field of a permanent magnet. However, by playing around with various magnets and creating different interactions it is possible to alter the magnetic field.
