Question 2

A virtual circular loop (with radius 0.2 m) lies on the screen. There is a uniform electric field everywhere on the screen, pointing out of the screen at 45 degrees relative to the screen. The magnitude of the electric field changes with time as 5t N/C, where t is time.

(a) Calculate the electric flux through the loop at t = 2 sec.

Question 1 (cont.)

(b) Calculate the magnitude of the voltage induced in the conducting loop.

Question 1 (cont.)

If, instead, the smaller circle is the cross section of the solenoid and the larger circle is the conducting loop (i.e., the conducting loop is outside the solenoid),

(d) Calculate the magnetic flux though the conducting loop at time t = 2 sec.

Question 1

In Figure 1, the larger circle (with radius 0.3 m) is the cross section of a solenoid. The solenoid has 100 turns per meter and carries a counter-clockwise current that increases with time as 2t ampere, where t is time. The smaller circle (with radius 0.2 m) is a conducting loop. The two circles lie on the screen. 

(a) Calculate the magnetic flux though the conducting loop at time t = 2 sec.

The magnetic flux through the surface bounded by a virtual loop changes with time. Which of the following statement is FALSE?

A planar virtual loop is in a uniform electric field. The field points into your screen, perpendicular to the screen. The electric flux through the surface bounded by the loop is maximum for which of the following case

There is a uniform magnetic field pointing into your screen, perpendicular to the screen. The magnitude of the field is increasing with time. A planar conducting loop lies on the screen. Which of the following statement is FALSE?
