1.
a) A current of 0.5A flows through a coil having an inductance of 1.5H. Determine the magnetic energy stored in it
(2 marks)
b) A 20cm length conductor is caused to move in a magnetic field of 0.5T at a speed of 20m/s. Determine the
emf induced in the conductor.
c) A 25cm current carrying conductor is placed at right angle to a magnetic field of 2.5T. Knowing that the
current through the conductor is 20A,
