Two circular loops of wire surround an insulating rod as in Figure P20.53. Loop 1 carries a current I in the clockwise direction when viewed from the left end. If loop 1 moves toward loop 2, which remains stationary, what is the direction of the induced current in loop 2 when viewed from the left end?

A segment of wire 7.5 cm long is moving at a velocity of 3.26 m/s toward a parallel (much longer) wire which carries a current of 3.46 A. At a particular instant the wire segment is 7.4 cm away from the long, current-carrying wire. What is the induced emf (voltage) between the two ends of the wire segment?

Chapter 30, Concept Question 04 The figure shows two circuits in which a conducting bar is slid at the same speed v through the same uniform magnetic field and along a U- shaped wire. The parallel lengths of the wire are separated by 24 in circuit 1 and by L in circuit 2. The current induced in circuit 1 is counterclockwise. e (2) Is the magnetic field into or out of the page? Into Out of Is the current induced in circuit 2 clockwise or counterclockwise? Counterclockwise Clockwise Is the emf induced in circuit 1 larger than, smaller than, or the same as that in circuit 2? Larger The same as Smaller

As a diligent physics student, you carry out physics experiments at every opportunity. At this opportunity, you carry a 1.15 m long rod as you jog at 3.17 m/s, holding the rod perpendicular to your direction of motion. What is the magnitude B of the magnetic field that is perpendicular to both the rod and your direction of motion and that induces an EMF of 0.287 mV across the rod? Express the answer in milliteslas. B = mT

A 24-turn circular coil of wire has diameter 1.09 m. It is placed with its axis along the direction of the Earth's magnetic field of 47.0 µT and then in 0.200 s is flipped 180°. An average emf of what magnitude is generated in the coil? x What is the change in the magnetic flux during this time interval? mV

Two circular loops of wire surround an insulating rod as inFigure P20.53. Loop 1 carries a current I in the clockwise directionwhen viewed from the left end. If loop 1 moves towardloop 2, which remains stationary, what is the direction of theinduced current in loop 2 when viewed from the left end?

A loop of wire lies flat on the xy plane and has a magnet above it with the north side pointed down. The magnet moves in the +z direction away from the loop. If we looked at the loop of wire from above, what is the direction of the induced current?   No current is induced Counterclockwise Clockwise

A 7.00 diameter loop with a resistance of 0.700 Ω is in an increasing magnetic field of 1.20 T/s as shown in the image. What is the magnitude and direction of the induced current? 6.41 A, clockwise 0.00660 A, counterclockwise 6.41 A, counterclockwise 0.00660 A, clockwise

Three loops of wire move near a long straight wire carrying a current as in Figure P20.9. What is the direction of the induced current, if any, in (a) loop A, (b) loop B, and (c) loop C. A B I C Figure P20.9

The bolt of lightning depicted in Figure P20.61 passes 200. mfrom a 100-turn coil oriented as shown. If the current in the lightning bolt falls from 6.02 x 106 A to zero in 10.5 µs, whatis the average voltage induced in the coil? Assume the distanceto the center of the coil determines the average magneticfield at the coil’s position. Treat the lightning bolt as along, vertical wire.
