Question

Exercise 29.24 A rectangle measuring 30.0 cm by 40.0 cm is located inside a region of a spatially uniform magnetic field of 1.25 T. with the field perpendicular to the plane of the coil (the figure (Figure 1) ). The coil is pulled out at a steady rate of 2 00 cm/s traveling perpendicular to the field lines. The region of the field ends abruptly as shown. Part A Find the emf induced in this coil when it is all inside the field. Part B Find the emf induced in this coil when it is partly inside the field. Part C Find the emf induced in this coil when it is all outside the field.

Explanation / Answer

This could be determined by using the formula of motional emf

emf = VBL = 2(10-2)(1.25)(40)(10-2)

emf = 0.01V

b) emf = 0.01V

c) When it is out side the field induced emf = 0 V
