Electricity from the Earth's magnetic field via electromagnetic induction

This experiment demonstrates the generation of electric current through electromagnetic induction using the Earth's magnetic field. A coil with copper wire with approximately windings is rotated. As the wire loops rotate within the Earth's magnetic field, the changing magnetic flux induces a current in the wire. This induced current is measured with a multimeter.

Note that the "law of conservation of energy" applies in this experiment. Mechanical energy to rotate the solenoid is transformed into electrical energy through electromagnetic induction.
