Question

5. Figure shows two coils placed close to each other. When the current through one coil is
increased. What will be the direction of current in second coil.
B
Rheostat
Observer
A​

Answer 1

Answer:

there will be ripulion between A and B alternated

Answer 2

The direction of current in the second coil is along CBA

Explanation:

• When current flows in the first coil, current is induced in the second coil - Electromagnetic induction.

• As per Lenz's law , direction of the electric current which is induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes changes in the initial magnetic field.

• Since the current in the first coil is along ABC, in the second it will be the opposite,i.e, along CBA .
