Question

(a) What is the average induced emf in the coilduring this rotation? in mV
(b) If the coil is made of copper with a diameter of 0.900 mm, whatis the average current that flows through the coil during therotation? in A (a) What is the average induced emf in the coilduring this rotation? in mV (b) If the coil is made of copper with a diameter of 0.900 mm, whatis the average current that flows through the coil during therotation? in A A circular conducting coil with radius 2.70 cm is placed in a uniform magnetic field of1.020 T with the plane of the coilperpendicular to the magnetic field as shown. The coil is rotated180degree about the axis in 0.222 s.

Explanation / Answer

   a) The mangitude of the average induced emfduring this rotation is                 = B (r^2)/(t)       Here B = 1.020 T               r = 2.70*10^-2 m               t = 0.222 s substiute the values.
