(a) What is the change in B (dB)?
(d) What is the magnitude of current induced in the coil?
(a) Change in B field is given by dB = Bf - Bi = 2 - 4 = -2 T
(b) As change in time is dt = 0.10s we know the rate of change of field B as ...
A coil with N = 25 loops having an area of A = 0.15 m2 and a resistance of 150 Ohms is perpendicular to a magnetic field, B, that decreases from Bi =4.0 T to Bf =2.0 T in a time of dt = 0.10 s.
The following parameters are determined using algebraic techniques combined with Faradays Law and Ohms Law
The change in B (dB)?
The rate of change in magnetic flux through the coil?
The magnitude of the emf induced in the coil?
The magnitude of current induced in the coil?
