Transcript
Producing Magnetism From Electric Currents ⢠In a solenoid, the magnetic field of each loop of wire adds to the strength of the magnetic field of the loop next to it. ⢠A solenoid has a north (incoming current) and south (outgoing current) pole. ⢠The strength of the magnetic field of a solenoid depends on the number of loops of wire and the amount of current in the wire. ⢠An electromagnet is a strong magnet created when an iron core is inserted into the center of a current-carrying solenoid.
