A) magnetic flux is negative ,so i am considering negative as downward
B) according to lenz's law
the induced current is counterclockwisedirection
the induced current is in direction
Physics question. Suppose that a bar magnet falls through a conducting hoop of wire with its...
For the following situations involving a bar magnet and circular conducting loop, indicate the direction of the induced current in a diagram and explain your reasoning clearly. (a) You move the north pole of the magnet towards the loop, keeping the magnet aligned with the symmetry axis of the loop. (b) You move the south pole of the magnet towards the loop, keeping the magnet aligned with the symmetry axis of the loop. (c) You move the north pole of...
Conceptual: A conducting loop of wire is oriented horizontally, and a magnet is falling downward, through the loop. (a) Draw the direction of the induced current that flows in the loop as the magnet falls downward. (b) Sketch and label the magnetic field lines that are created by the induced current in the loop. (c) Does this create an attractive or repulsive force between the loop and magnet?
Physics Pre-Lab Magnetism and Induction Name: UserID (e.g. abc123): Pre-Lab Questions: 1. The figures below indicate currents running through a flat circular loop of wire that is nearly perpendicular to the plane of the page. In which of these figures will the magnetic field at the center of the loop point toward the bottom of the page? (The larger arrow is on the part of the loop closest to you.) 2. In the figures at right, a magnet is shown...
Magnetic induction lab: 5 questions 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 vertical bar magnet is dropped through the center of a horizontal loop of wire, with its south pole leading....
answer all Q pls 8. A bar magnet is dropped through a loop of copper wire as shown. Recall that ou magnet, magnetic field lines point away from a north pole and toward a south p positive direction of the induced current I in the loop is as shown by the arrows on the loop, the variation of I with time as the bar magnet falls through th by which of the following graphs (the time when the midpoint of...
If you drop a bar magnet down a tube made of conducting material (like copper or aluminum) something interesting happens: the bar magnet does not simply accelerate all the way down under the influence of gravity. Instead, there are forces that oppose the motion and cause the bar magnet to descend at essentially a constant velocity. Suppose you do this two times: once with the north pole of the magnet facing down and the second time with the north pole...
1) Which of Maxwell's equations below predicts an induced magnetic field due to changes in an electric field? A) #Edi = 9 B) B. dA= 0 D$B.ds = Hole + Hope E) All of them 2) In the figure, two parallel wires carry currents of magnitude / as shown. The current is decreasing with time. A rectangular loon is midway between the wires. What is the direction of the net magnetic field in the region between the wires and that...
A bar magnet is oriented above a copper ring, as shown in the figure. The magnet is dropped and passes completely through the ring. As viewed from above, what is the direction of the current induced in the ring after the magnet has completely passed through the ring and is somewhat below it? There is no current in the ring. counterclockwise clockwise
