In the above problem (example 3) what is the emf induced when current is reduced to zero and then increases again to 1.5 A in reverse direction in 25ms?

An average induced emf of 0.20 V appears in a coil when the current in it is changed from 5.0A in one direction to 5.0 A in the opposite direction in 0.2 sec.

An average induced emf of 0.20 V appears in a coil when the current in it is changed from 5.0 A in one direction to 5.0 A in the opposite direction in 0.20 s. find the self inductance of the coil.

Predict the direction of induced current in metal rings 1 and 2 when current I in the wire is steadily decreasing .

An average induced e.m.f. of 1V appears in a coil when the current in it is changed from 10 A in one direction to 10A in opposite direction in 0.5 sec. self-inductance of the coil is

When a certain curcuit consisting of a constant e.m.f. E an inductance L and a resistance R is closed, the current in it increases with time according to curve 1. After one parameter (E, L or R) is changed, the increase in current is closed second time. Which parameter was changed and in what direction?

Two long conductors, separated by a distance d carry current I_(1) and I_(2) in the same direction . They exert a force F on each other. Now the current in one of them is increased to two times and its direction is reversed . The distance is also increased to 3d . The new value of the force between them is

A long solenoid of cross-sectional area 5.0 cm^2 is wound with 25 turns of wire per centimetre. It is placed in the middle of a closely wrapped coil of 10 turns and radius 25 cm as shown. (a) What is the emf induced in the coil when the current through the solenoid is decreasing at a rate -0.20 A//s ? (b) What is the electric field induced in the coil?

An average emf of 20 V is induced in an inductor when the current in it is changed from 2.5 A in one direction to the same valute in the opposite direction in 0.1 s. Find the self inductance of the inductor.

A centipede was crawling in a straight line. First it crawled for 8 (3)/(7) inch, then it crawled in the reverse direction for 5 (5)/(8) inch. Once again it reversed direction and crawled for 11 (1)/(2) inch in the original direction. How far away was it finally from the starting point?
