Electromagnetic induction was first observed by this American scientist in 1831.

Around the same year, this English scientist conducted independent experiments on electromagnetic induction.

It is induced by the relative motion between the conductor or coil and the magnetic field.

It "forces" the charges through and around the wire and can be compared to a battery's voltage.

The changing magnetic field causes emf to be induced through the coil, causing current to flow.

Equation of Voltage

voltage, magnetic field, length, speed

It states that an induced current is always in such a direction that its own magnetic field acts to oppose the effect that created it.

It is a coil of wire.

It is a device that converts mechanical energy into electrical energy by applying the principle of electromagnetic induction.

Current is produced in an electric generator by rotating a wound coil, which is called?
