QUESTION 3 3.1 A 480cm long conductor is placed at a right angle to the magnetic field. When the conductor is moved through a magnetic field at a speed of 1.782m.s". Calculate the magnetic flux density of the field if the e.m.f generated in the conductor is 12.4v. (5) 3.2 A four-pole generator has a magnetic flux of 144me per pole. The armature is driven at 'r'50rfmin. Calculate the average value of the e.m.f generated in one of the armature conductors while it is moving through the magnetic flux of one pole. (5) [10]
