EM6.6 Magnetic Domains
This is an array of magnetized arrows. A magnet can be brought near to change the direction of the arrows. They align themselves according to the magnetic field. However, they reform into domains when the field is removed. Once arranged, the arrows will only realign when another magnet is brought near. This can be used with a Helmhotz coil on the vu graph to create a hysteresis representation.
