Question

which of the following involves electromagnetic induction [a] a rod is charged with electricity [b] an electric current produced [c] a magnetic field exerts force on a current carrying wire [d] the relative motion between a magnet and a coil produces an electric current

Answer 1

Answer:

in my opinion correct answer is (d).

Explanation:

Answer 2

The relative motion between a magnet and a coil produces an electric current or option (d) involves electromagnetic induction.

• In electromagnetic induction, a current is produced but it has two requirements:

1. Either a stationary conductor should be placed in a moving magnetic field or

2. The conductor should move continuously when placed within a stationary magnetic field.

• This principle was proposed by Michael Faraday in 1831.

• AC generators, electrical transformers, magnetic flow meters, etc. all work using this principle.
