K.C.S.E Physics Q & A - MODEL 2009PP2QN10
​Figure 5 shows a magnet being moved towards a stationary solenoid. It is observed that a current flows through the circuit in a direction Q to P.
​Explain:
(i) How the current is produced (ii) Why the current flows from Q to P
answer
(i) Movement of magnet causes flux linkage to change
E.M.F is produced in the cell. (ii) When 1 flow from Q to P, a N. pole is created which opposes the approaching pole (long’s law).
