GCSE Physics - Generator Effect / Electromagnetic Induction #81

The video explains electromagnetic induction, where a potential difference is induced in a wire moving through a magnetic field. It highlights that a current is generated when the wire forms a closed circuit. The video also discusses how the strength of the magnetic field, speed of movement, and number of coil turns affect the induced potential difference. Additionally, it covers how moving a magnet in and out of a coil induces a current, with direction changes based on magnet orientation.

Describe how the number of turns in a coil affects the induced potential difference.

What is the effect of moving a magnet in and out of a coil of wire?
