  • Electromagnetism 147 Worked Example 5.3 Q A coil when linked by a fl ux which changes at the rate of 0.1 Wb/s, has induced in it an emf of 100 V. Determine the number of turns on the coil.

A negative value for number of turns makes no sense. 5.4 EMF Induced in a Single Straight Conductor Consider a conductor moving at a constant velocity v metre per second at right angles to a magnetic fi eld having the dimensions shown in Fig. 5.7 . The direction of the induced emf may be obtained using Fleming ’ s righthand rule, and is shown in the diagram. Equation (5.1) is applicable, and in this case, the value for N is 1.dV Fig. 5.7 Thus,ddvolt, and since is constantthen voltbutetetBAeBAt weberso
