A conducting ring is placed near a solenoid as shown in Fig.3.21. Find the direction of the induced current in the ring.
(a) At the instant the switch in the circuit containing the solenoid is closed.
(b) After the switch has been closed for a long time.
(c) At the instant the switch is opened.

The steady - state current through L_(1) after the switch has been closed for a very long time is

Find current through the battery (a) just after the switch is closed (b) long after the switch has been closed

Find current through the battery (a) just after the switch is closed (b) long after the switch has been closed

Find the current through the battery (i) just after the switch is closed. (ii) long after the switch has been closed.

Find the current through the battery (i) just after the switch is closed. (ii) long after the switch has been closed.

In Fig. switch S is closed for a long time. At t = 0 , if it is opened, then

In Fig. switch S is closed for a long time. At t = 0 , if it is opened, then

In Fig. switch S is closed for a long time. At t = 0 , if it is opened, then

In the circuit as shown in figure the switch is closed at t = 0 . At the instant of closing the switch

A small, circular ring is inside a larger loop that is connected to a battery and a switch as shown in Fig. 3.25. Use Lenz's law to find the direction of the current induced in the small ring (a) just after switch S is closed, (b) after S has been closed for a long time, ( c) just after S has been reopened after being closed for a long time. ltbr.
