A bar magnet is held vertically above a horizontal metal ring
A bar magnet is held vertically above a horizontal metal ring, with the south pole of the magnet at the top (Figure 22.63). If the magnet is lifted straight up, will current run clockwise or counterclockwise in the ring, as seen from above?

Q4 A bar magnet is held above a loop of wire in a horizontal plane, as shown in Figure. According to the Lenz's law (write the Lenz's law), find the direction of the induced current through the resistor (a) while the magnet is falling toward the loop and (b) after the magnet has passed through the loop and moves away from it (draw the magnetic field lines of both the magnet and loop).

A vertical bar magnet is dropped through the center of a horizontal loop of wire, with its south pole leading. At the moment just before the south pole passes through the loop, what is the direction of the induced current in the loop (viewed from above)? 2. Explain your answer to the previous question. 3.

A bar magnet is moved (in the plane of the page) with respect to a single-tur of radius 5.00 cm as shown (the coil lies in a plane perpendicular to the di of the bar magnet). Over a time interval of 0.150 s, the magnitude of the magnetic field at the coil varies from 0.640 T to 0.240 T. The resistance of coil is 2.50 Ohms. Assume that the magnetic field is uniform over the bounded by the coil. 4....

Physics question.
Suppose that a bar magnet falls through a conducting hoop of wire with its north pole facting downward. Three consecutive snapshots of its descent are shown below. For each snapshot, state whether: the magnetic flux through the loop is upward, downward, or zero; the induced current is clockwise, counterclockwise, or zero, from the point of view of an observer looking down from above the loop. Make a qualitative sketch of the induced current versus time (taking counterclockwise as...

2. A bar magnet is dropped through a
loop of wire as shown. Looking at the loop from above,
a) What is the direction of the
current as the magnet enters the loop from the top?
b) What is the direction of the
current as the magnet as it leaves the loop from the bottom?
c) What is the direction of the
current at the instant it is in the middle half above and half
below?
