Electromagnet Induction demonstration. This video shows the operation of an electromagnetic induction. The coil consists of two windings of copper wire, "the primary coil 1, the secondary coil 2." The primary coil is composed of 220 turns of wire 0.40 mm. The secondary coil is composed of 120 turns of wire from 0.85 mm. The system supply voltage is 28-30 volts AC.
Explanation of the operation:
in the spool of wood were wrapped two coils of copper wire separate between them. When in the central hole of the spool is inserted an iron core, the coil reacts by creating an electromagnetic field. Conversely, by exchanging the terminals of the coils, the electromagnetic force is canceled at the terminals of the wires.
