Ferromagnetism

Ferromagnetism is a mechanism by which some materials show magnetic properties. Iron and magnetite, an oxide of iron, are two naturally occurring materials that show the property of ferromagnetism. The word ferromagnetism is derived from the Latin name of iron, "Ferrum" as it was the first observed material to show such property. The property of ferromagnetism is shown by only a few substances such as iron, nickel, cobalt, and their alloys. Some transition metals and alloys of rare-earth metals also show ferromagnetism.

Question

(a) (i) A conductor moves with a velocity of 15 m/s at an angle of (a) 90°, (b) 60 and (c) 30• to a

face is 5 µWb, find the magnitude of the induced e.m.f. in each case.
