Introduction: Magnet Switch

Difficulty of realization 7/10

Step 1: How It Work

Picture of How It Work

With this experiment I want to show how to create a switch for permanent magnets.
Obviously you can not turn off the magnetic field of a permanent magnet, but by playing with more than one magnet and creating interaction with their fields you can get interesting results. What you need for this experiment are 3 equal magnets and iron bars to cut the required size, add the pieces as you see in the video and you will have built a permanent magnet with ON / OFF switch In the images up here you see the shape of the fields that are generating if we have all the magnets with the same polarity (attraction) or turning the switch with alternating polarity (no attraction).

Step 2: How It Make

Picture of How It Make

To build this switch i used:

2 iron bars 12x12x70 mm
2 pieces of iron 15x4x26 mm
1 piece of iron 15x4x20 mm
3 neodymium magnets 12x12x12 mm
a suitably cut plastic cap to build a ring nut and rotate the top portion of the switch
