Question

A magnet is inserted into the centre of a coil and an e.m.f.is Induced across the coll. The magnitude
of the induced current depends on:
A) The diameter of the coil.
B) The strength of a magnet.
C) The thickness of the wire with which the coil is made.
D) All of the above.​

Answer 1

Answer:

The correct answer to the que is D) All of the above.​

Explanation:

The factors on which the magnitude of induced current in the coil depends?

Induced e.m.f for a coil of wire depends on four things:

• Magnetic strength of the core in the coil of wire. (stronger --> bigger emf)
• Number of turns of wire in the coil (more turns --> bigger emf)
• The cross-sectional area of the coil (bigger area --> bigger emf). ...
• How fast we move the magnet into/out of the coil.
