Indicate the direction of the current in the loop in the exa

Indicate the direction of the current in the loop in the examples below:

Solution

here ,

we can find the direction of current using Lenz\'s law

a)as the current is decreasing , the induced magnetic field will be as same direction like applied field.

the direction of current in the loop is ANTI CLOCKWISE.

b)
as the current is increasing , the induced magnetic field will be as oposite direction like applied field.

the direction of current in the loop is CLOCKWISE.

c)

as the current is decreasing , the induced magnetic field will be as same direction like applied field.

the direction of current in the loop is ANTI CLOCKWISE.

d)

as the current is constant

there is no current in the loop

e)

as the magnetic flux in the loop will increase when it moved towards the wire.

the induced magnetic field will be as oposite direction like applied field.

the direction of current in the loop is CLOCKWISE.
