Finally, don't forget to add a loop of wire or twine to the top of the wreath so you can hang it.

Make a loop of wire that will fit round your head.

The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in the loop constant.

The loop of wire at the tip may be made of platinum or nichrome, the latter being inferior but less expensive.

This magnetic field would induce a current in an adjacent longer secondary loop of wire.
