Electromagnet		a device that converts eletrical energy to mechanical energy
Electric motor		They produce magnetic fields
Electric Currents		a long,wound coil of insulated wire
Electron Spin		produces a tiny magnetic field around in every electron
Galvanometer		strong magnet created when an iron core is inserted into the center of a current-carrying solenoid
Solenoid		a microscopic magnet region composed of a group of atoms whose magnetic fields are aligned in a common direction
Hans Christian		an instrument that measures the amount of current in a circuit
Domains		man who first experimented with the effects of an electric current on the needle of a compass
