Question
Transcribed Image Text:3. A 100-loop square coil of wire, with side length d = 5.00 cm and total resistance 100 Q, is
positioned perpendicular to a uniform 0.600-T magnetic field (Figure 2). It is quickly
pulled from the field at constant speed (moving perpendicular to B) to a region where B
drops abruptly to zero. At t = 0, the right edge of the coil is at the edge of the field. It
takes 0.100 s for the whole coil to reach the field-free region.
Find
a. the rate of change of flux through the coil.
b. the induced emf and current.
c. What is the magnitude and direction of the magnetic force FM on the coil?
