a.Calculate the magnetic flux linkage for 100 coils between a magnetic field of B = 0.9 T and the coils have an area of 0.3 m2 forming an angle of 45° between them.
b.If the magnetic field changes in 0.3 s to B= 0.4 T and the coils have a frequency of 50 Hz. Calculate the Emf produced.
c. Suppose a single –turn coil of cross-sectional area 5.0 cm2 is at right angles to a flux density of 2.0 x 10-2 T, which is then reduced steadly to zero in 10s. What is Emf induced?
