7) You have been asked to check the working of transformers in
the flight system, by
verifying the results obtained from the following questions -
a. A conductor 300mm long moves at a uniform speed of 4m/s at right
angles to a
uniform magnetic field of flux density 1.25T. Determine the e.m.f
induced in the
circuit.
b. The energy stored in the magnetic field of an inductor is 80J,
when the current
flowing in the inductor is 2A. Calculate the inductance of the
coil.
