Electromagnet

This is an attempt at a printable/castable electromagnet. The coil is made from plastic castings and low-melt alloy. There is one base-disk and four coil-disks in the assembly. Each coil-disk has 1.5 turns, so there is a total of 6 turns in the coil. The magnetic core is made from iron powder mixed with epoxy.

This electromagnet did not work very well. With a current of tens of amps it can barely move a paperclip. Poor performance is probably mostly due to the low permeability of the
