State Lenz's Law.
A metallic rod held horizontally along east-west direction, is allowed to fall under gravity. Will there be an emf induced at its ends? Justify your answer.

Text Solution

Verified by Experts

Yes, emf will be induced at the ends because magnetic lines of Earth.s magnetic field are cut by the rod. As a result, magnetic flux will change and hence, emf will he induced.

(a) When a small magnet is moved towards a sole- noid, an emf is induced in it. However, if a magnet is moved inside the hole of a toroid, no emf is induced. Explain. (b) A wire is kept horizontal along North-South direction. It is allowed to fall freely. How much emf will be induced across the ends of the wire due to presence of Earth’s magnetic field.

Assertion: Length of the metal rod is aligned along northsouth direction and is released from rest under gravity. Potential difference is generated along the length of the rod. Reason: When a metal rod is moved perpendicular to its length and parallel to magnetic field then magnetic force on electrons generates electric field along the length of rod.
