A single loop of wire with an area of 0.0920 m2 is in a uniform magnetic field that has an initial value of 3.80 T, is perpendicular to the plane of the loop, and is decreasing at a constant rate of 0.240 T/s.

a. What emf is induced in this loop?
b. If the loop has a resistance of 0.600Ω, find the current induced in the loop.

Induced emf in the loop is 0.02208 volt.

Induced current in the loop is 0.0368 A.

Explanation:

Given that,

Area of the single loop,

The initial value of uniform magnetic field, B = 3.8 T

The magnetic field is decreasing at a constant rate,

(a) The induced emf in the loop is given by the rate of change of magnetic flux.

(b) Resistance of the loop is 0.6 ohms. Let I is the current induced in the loop. Using Ohm's law :

Hence, this is the required solution.

1= 26.17

2= 1.17

3=30.86

4=5.86
