A circular wire loop of radius rrr = 13 cmcm is immersed in a uniform magnetic field BBB = 0.555 TT with its plane normal to the direction of the field. If the field magnitude then decreases at a constant rate of −1.0×10−2 T/sT/s , at what rate should rr increase so that the induced emf within the loop is zero?
A circular loop of wire of radius r = 1.0 m is placed in a region where an external uniform magnetic field is perpendicular to the plane of the loop. The external magnetic field vector points in, perpendicular to the page. During the course of 0.150 seconds, the field magnitude B is DECREASED uniformly (i.e., linearly in time) from 0.64 T to 0.25 T.
(a) What is the direction of the induced current i in the loop, clockwise or counterclockwise. Please indicate this direction by drawing a curved arrow at the wire. What is the direction of the induced magnetic field, in or out?
(b) What is the magnitude ε of the average induced electromotive force (emf)?
(c) If the resistance of the wire is 2.00 ohms, then what is the magnitude of the induced current? How much heat is created in a period of 1.0 minute?
An elastic circular conductor expands at a constant rate with time so that its radius is given by r (t) = r_0 + vt, where r_0 = 0.1m and v = 0.015m / s. The loop has a constant resistance of R = 12Ω and is placed in a uniform magnetic field of magnitude B_0 = 0.75T, perpendicular to its plane, as shown in the figure. Find the direction and magnitude of the induced current, i_ {ind}, at t = 5s.

- A conducting single-turn circular loop with a total resistance of 5.00 is placed in a time-varying magnetic field that produces a magnetic flux through the loop given by B = a + bt2 ct3, where a = 4.00 Wb, b = 11.0 Wb/s2, and c = 6.00 Wb/s3. B is in webers, and t is in seconds. What is the maximum current induced in the loop during the time interval t = 0 to t = 3.50 s?arrow_forwardA conducting rod is pulled horizontally with constant force F = 5.00 N along a set of rails separated by d = 0.56 m. A uniform magnetic field B= 0.60 T is directed into the page. There is no friction between the rod and the rails, and the rod moves with constant velocity v = 4.00 m/s. Using Faraday's Law, calculate the magnitude of the induced emf (in V) around the loop in the figure that is caused by the changing flux.arrow_forward
