A single loop of wire with an area of 0.0860m^2 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 0.140 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.

Answer:

Explanation:

Magnetic field B = 3.8 T

Magnetic flux Φ = BA , A is area

rate of change of flux

= dΦ / dt

d ( BA) /dt

= A  x  dB / dt

= .086 x .14

emf induced

= .086 x .14

= .012 V

b )

Current

= induced emf / resistance

=  .012  / .6

= .02 A
