Given the task of describing the theory of magnetic domains

Ok, I have no idea what to write. I dont know any of this =/

You have been given the task of describing the theory of magnetic domains to a Class of 5th graders. You have enough large paper arrows to give one to each student. Describe your plan to show them the domain nature of

A non-magnetic material A permanent magnet An electromagnet

Answer #1

Ok, magnetic domains show the direction that “mini magnets” are pointing. So for the non-magnetic, you’ll want to get all the kids to point their arrows in different directions. Get small groups to point in the same direct, they will form a domain. The idea is all the different directions of the mini magnets cancel so there is no over all magnetic force.

For the permanent magnet get all the kids to point in the same direction, thus forming one big domain, and an overall magnetic field.

For the electromagnet, get all the kids to stand pointing in different directions, you then walk though them (acting as the electric current) and get them to point in the direction you’re walking. Then when you stop get them to point randomly again, which shows the breakdown of the magnetic field after the current has stopped.
