Question

A coil of insulated copper wire is connected to a galvanometer forming a loop and a magnet is: A: Held stationary B: Moved away along its axis C: Moved towards along its axis There will be a induced current in

Answer 1

There will be induced current if:

• The magnet is moved away along its axis.

• The magnet is moved towards along its axis.

This can be explained on the basis of Faraday's Law of Electromagnetic Induction:

• Faraday's Law states that current will be induced in a wire only if there is a change in the magnetic flux passing through the coil of wires.

Now , when the magnet is moved away or towards the copper wire along its axis, there is change in the magnetic flux.

Hence , a current is induced.

$i = \dfrac{voltage}{resistance}$

$\boxed{ = > i = \dfrac{( \frac{d \phi}{dt} )}{resistance} }$
