An electric current is induced if a bar magnet is moved through the center of the wire coil. Option B is correct.
What is the faraday law of electromagnetic induction?
According to Faraday's law of electromagnetic induction, the rate of change of magnetic flux linked with the coil is responsible for generating emf in the coil resulting in the flow of amount of current.
To increase the current, we need to increase the EMF
so we can increase it by
1) increasing the number of turns
2) increase the area of the loop
3) by moving the magnet faster
If a bar magnet is positioned close to the wire loop, an electric current will be induced.
If a wire loop is looped around the bar magnet, an electric current is induced. A bar magnet can produce an electric current by passing it through the wire loop.
An electric current is induced if a bar magnet is moved through the center of the wire coil.
Hence option B is correct.
