How does a magnetic base work?

Magnetic bases can be one of two varieties: those with lever switches and those with push buttons
Although the ON/OFF for the magnet may vary, the way the system works is still the same.

The magnetic base is made up of four parts: one part non-ferrous metal spacer (metal that does not contain iron), two parts iron and a third part which is the magnet.

In the bored-out centre of the base is a permanent magnet which it has a North and South pole.

The non-ferrous metal spacer, aluminium in this example, sits between two iron sections and has a hole bored through the centre of all three.

The magnet, when it is rotated or pressed, acts as the ON/OFF switch for the magnetic base.

It is the movement of the magnet which magnetises the iron, effectively switching the base on and off.

When the poles of the magnet are lined up with the aluminium spacer, the magnet is OFF.

When the magnet is rotated so the poles line up with the ferrous plates, the magnet is ON.
