Electromagnet

[eugenebrooks]

Mouser part number 653-G6E-134P-DC5 should do it,
the coil is designed for 5 volts, and the relay drive
current is 40 ma. We selected this one to drive
transistors for a programmable battery load tester.

The spdt relay handles 3 amps.
If you need to control a bigger current,
use this relay to actuate a bigger one.

If you were to find a miniature relay designed for 5 volts and less than 85ma coil current you could use it to control the current to a magnet structure. The source for the magnet would need to be external to the controller (so as not to draw excessive currents.) and the relay contacts need to be able to handle whatever current the electro magnet requires.
