INSTRUCTION: ANSWER ALL QUESTIONS
1. Explain the phenomenon of self-induction.
(2 marks)
2. Two coils P and Q are arranged coaxially and close to each other. The coils have
500 turns and 800 turns respectively. A current of 5.0 A in coil P produces a flux of
0.20 mWb in each turn of coil P and a flux of 55 μWb in coil Q. Calculate
i. the self-inductance of coil P.
ii. the mutual inductance of the two coils.
iii. the emf induced in coil Q when the current in coil P changes at a rate of 2.0
As–1.
(6 marks)
3. Figure 1 below shows a 0.6 m long metal bar being pulled to the right at a steady
speed of 5.7 ms-1 perpendicular to a uniform 0.7 T magnetic field. The metal rails
are connected to a 5 Ω resistor.
