a. Explain what is meant by a magnetic flux linkage of 1 Wb.
b. This is a graph of magnetic flux density through a 240 turn coil with a cross-sectional area 1.2 × 10⁻⁴ m² against time

i. Determine the maximum rate of change of flux in the coil.
ii. Determine the maximum magnitude of the induced e.m.f. in the coil.
iii. Sketch a diagram to show the induced e.m.f. varies with time. Mark values on both the e.m.f. and time axes.
