Homework Answers
a. If we increase IA , the . magnetic field will increase in the loop B. According to lenz law, current will be induced in loop B in clockwise direction .
b. If we decrease IA , the . magnetic field will decrease with time in the loop B. According to lenz law, current will be induced in loop B in counter clockwise direction .
c.If we tilt the loop B, . magnetic flux will decrease in the loop B. According to lenz law, current will be induced in loop B in counter clockwise direction .
d. When loop B is at the halfway as shown, B due right arc of loop A can be assumed to cancel out while . magnetic field due to left arc of loop A will decrease. So, current will be induced in loop B in counter clockwise direction .

An decreasing current I flows in an elliptical loop of wire. Two
loops of wire are placed as shown. Why is the flow of induced
current counterclockwise for loop 1? I thought that mutually
induced emf equals (-)M(di/dt). Doesn't the negative sign mean that
the mutually induced emf (and hence the induced current) will be in
the opposite direction of the rate of change of current? So why
wouldn't the induced current for loop 1 be clockwise?

A square loop of wire with side length 10 cm is moving to the right with constant speed of 16 m/s. The loop has total resistance of 0.8 ohms. It begins in a region with no magnetic field, then enters a region of magnetic field (wider than 10 cm) with a strength of 0.5 T pointing into the page. Finally it leaves the field. 21) While entering the field what is the direction of the induced current as seen from above...
