Figure 1 shows a conducting loop of area 20 cm^2 that lies in the x-y plane, if B= -5t a_z Wb/m^2, Determine the value and the direction of the induced current Determine the voltage v_1 and v_2 across the resistors
Solution
(a) EMF:
=BLv = -5* 20*10-4 = 0.01V
Current:
i = /R = 0.01/15 = 0.6 mA.
If a coil is shrinking in a B field pointing into the page, the direction of the induced current is CLOCKWISE.
(b) V1 = IR1 = (0.6)(10) = 6 mV.
V2 = IR2 = (0.6)(5) = 3 mV.
