A horizontal straight wire 10 m long extending from east to west is falling with a speed of 5.0 m s–1, at right angles to the horizontal component of the earth’s magnetic field, 0.30 × 10–4 Wb m–2. (a) What is the instantaneous value of the emf induced in the wire? (b) What is the direction […]
An electric generator works on the principle of electromagnetic induction. When a coil is rotated in the presence of a strong magnet, electricity is produced.See the video below for demonstrating a simple electric generator.
