Question

1) The circular loop shown at the below is rotating in the direction indicated in a constant magnetic field with direction out of the page. At the time drawn, the normal of the loop makes an angle of 45? with the magnetic field. What is the direction of the current induced in the loop? At the time shown, the right side of the coil is moving into the page and the left side out of the page.

(a) No current is induced. (b) clockwise (c) counterclockwise

2) The two finite solenoids in the figure are moving toward one another. The left solenoid is powered by a battery producing a nearly constant current. Is a current induced in the right solenoid? If a current is induced, what is the direction of the induced current in the right solenoid as the current flows through the resistor R2 connected to the right solenoid?

(a) The current is zero.

(b) to the left of the page

Magnetic Field Out of Page conducting ako

Explanation / Answer

direction of incuded current always opposes the the cause of its motion

i.e here B is out of the page and

when loop is moved inwards, the direction of current will be CCW

option C it is

---------------------------------------------------------

2. from lens law

induced current will be from left to right
