10.1 The arrangement of apparatus to demonstrate Faraday’s law of
electromagnetic induction is shown below.
10.1.1 State Faraday’s law of electromagnetic induction in words. (2)
10.1.2 State TWO ways in which the deflection on the galvanometer can be
increased. (2)
10.2 A coil with area 0,6 m2 is held with its axis coinciding with the direction of a
magnetic field of strength 0,4 T.
10.2.1 Calculate the magnetic flux linkage. (3)
In order to produce an emf of 9 V, the area of the coil, with its axis coinciding
with the direction of a magnetic field, is halved from 0,6 m2 to 0,3 m2 in
2 minutes.
10.2.2 Calculate the number of turns in the coil. (4)
