Part A. A metal rod is sliding along a U shape track in the plane (figure 1). A uniform magnetic field of B= 0.400 T is out of the page. If L=0.50m and V=3.00m/s, what is the magnitude of the induced EMF? What is the direction of the induced EMF? write direction here______________________

Part B according to Lenz Law, the direction of an induced current in a conductor will be that which tend to produce which of the following effect

A) enhance the effect which it produce.       B) produce the greatest volatage.       C) produce a greater heating effect    D) oppose the effect which it produce it.

Part C Refer to figure 2. A retangular loop wire is placed midway between two long straight parallel conductors. The conductors carr current i1 and i2 as indicated. If i1 is constant and i2 is increasing, then the net induced current in the loop is ?

a)Clockwise       b) counterclockwise

(Last) FiPST) Instructions: Draw pictures to aid in determining directions of magnetic fields and induced currents. Label Figure 1 Figure 2

Solution

Magnitude of the induced EMF = B L v

= 0.400 * 0.50 * 3.00

= 0.6 volts

The direction of the induced EMF is downwards

part B) D) oppose the effect which it produce it.

part C) b) counterclockwise
