When the switch is open, which of the following statements about the magnetic flux through the wire loop is true? Assume that the direction of the vector area of the wire loop is to the right.

The strength of the magnetic field at the center of a circular loop carrying current is directly proportional to:Options:A) The radius of the loopB) The square of the radius of the loopC) The current passing through the loopD) The resistance of the loop

The figure below shows two loops of wire having the same axis. The smaller loop has radius a andresistance R and the larger loop has radius b. The smaller loop is above the larger one, by a distance z,which is large compared to the radius b of the larger loop, (z >> b). Hence with current I through the largerloop as indicated, the consequent magnetic field is nearly constant through the plane area bounded bythe smaller loop. Suppose now that z is not constant but is changing at the positive constant rate v z = dz /dt > 0 (z increasing).(a) Determine the magnetic flux across the area bounded by the smaller loop as a function of z.

A solenoid with 500 loops has a cross sectional area of 8 cm2. It is suddenly transferred from a region where the magnetic field is 0.5 T to a region where there is no magnetic field. If the transfer requires 0.04 s and the resistance of the solenoid is 4 Ω. Determine : i)                    Magnetic flux
