At two later instants,
- Use Lenz’ law to determine whether the flux due to the current induced in the loop is positive, negative, or zero. Explain.
- Describe the current in the loop during this time interval.
Student 1: “The sign of the flux is the same as it was in part C. So the current here will also be counter-clockwise.”
Student 2: “I agree. If I think about the force on a positive charge on the leading edge of the loop. ¡t points towards the top of the page. That's consistent with a counter-clockwise current.”
Do you agree with either student? Explain.

- A straight conductor carrying current i=5.0 A splits intoidentical semicircular arcs as shown in Fig. 2. What is themagnetic field at the center C of the resulting circular loop?Please explain your result.arrow_forwardThe magnets shown in the sketch are dropped from rest through the middle of conducting rings. Notice that the ring onthe right has a small break in it, whereas the ring on the left forms a closed loop. (a) As the magnets drop toward the rings,do you predict that the magnet on the left has an acceleration that is greater than, less than, or the same as that of themagnet on the right? (b) Which of the following is the best explanation for your prediction?I. Both magnets fall with the acceleration due to gravity. The rings have no effect.II. The magnet on the left has a greater downward acceleration because the ring exerts an attractive force on it.III. The magnet on the right has the greater downward acceleration because the gap prevents a current that would exert arepulsive force on the magnet.arrow_forwardPlease just help with this question: What would be the terminal velocity of the rod if all the conditions of part (b) of the problem where held, except there was also friction with a kinetic coefficient of ?k=0.0215? (Note: I believe the answer for b) is the induced current of 0.049 A if it helps)arrow_forward
- As shown in the figure below, a particle of mass m having positive charge q is initially traveling with velocity vĵ. At the origin of coordinates it enters a region between y = 0 and y = h containing a uniform magnetic field B directed perpendicular out of the page.

(Use v as necessary.) vf = ?, path description = (straight line, semicircle, or circular arc) (c) Specify the path the particle takes and its final velocity, if v is less than the critical value. (Use v as necessary.) vf = ?, path description = (straight line, semicircle, or circular arc) (d) Specify the path the particle takes and its final velocity if v is greater than the critical value. (Use ? and v as necessary.) vf = ?, path description = (straight line, semicircle, or circular arc)arrow_forwardThe current I in a long, straight wire is constant and is directed toward the right as in Fig Conducting loops A, B, C, and D are moving, in the directions shown, near the wire. (a) For each loop, is the direction of the induced current clockwise or counterclockwise, or is the induced current zero? (b) For each loop, what is the direction of the net force that the wire exerts on the loop? Give your reasoning for each answer.arrow_forwardPART A: Two long wires, one of which has a semicircular bend of radius R and center P, are positioned as shown below. If both wires carry a current, how far apart must their parallel sections be so that the total magnetic field at P is zero? Express a in terms of R. Does the current in the straight wire flow up or down? Explain. PART B: The infinite, straight wire shown below carries a current I1. The rectnangular loop, whose long sides are parallel to the wire, carries a current I2. What are the magnitude and direction of the total magnetic force on the rectangular loop due to the magnetic field of the long wire?arrow_forward
- A conducting rod of length L is moved with a uniform velocity (v), into a circular region of constant magnetic field B. (The small circles are to show the B-field is out of the page and perpendicular to the plane of the loop.). The field B is confined in a circular region and is perpendicular to the plane of the circle of radius R, and the moving rod. Let L = 2R, where R is the radius of the circular loop.

A permanent magnet in the shape of a right circular cylinder of length L and radius R is oriented so that its symmetry axis coincides with the z-axis. The origin of coordinates is at the center of the magnet. If the cylinder has uniform axial magnetization M, a.) determine U* (z) at points on the symmetry axis, both inside and outside the magnet, and b.) use the results of part a.) to find the magnetic induction Bz at points on the symmetry axis, both inside and outside the magnet.arrow_forward

The field inside the coil changes from 0.040 T to 0.025 T in a matter of 0.200 seconds. If the resistance of the coil is 6.00 Ohms, what is the magnitude and direction of the induced current in a coil as viewed from the side of the magnet?

The track lies in a vertical uniform magnetic field . Generator G produces a constant current i in the wire and the rails (even as the wire moves).
