A loop of wire sits in a uniform magnetic field, everywhere pointing toward you. Due to a changing magnetic flux through the loop, an induced current flows in the wire, clockwise as shown. The area of the loop is J. 1.63 m2 , and the magnetic field initially has magnitude K. 0.61 T. (a) Suppose that, over a time period of L. 1.47 s, the magnetic field changes from its initial value, producing an average induced voltage of M. 8.7...

Written Problem: Induction from a falling magnet We have a small magnet with a magnetic moment of m = 0.1 Am2 (remember: magnetic moment is defined as m = IA - see page 932 of book for the definition). We also have coils of wire. The coils are made out of 100 circular loops of a single wire. A single loop has a radius of 10 cm. The thickness of the wire has a circular cross section with a 0.5...

A magnetic field, strength 3T, has a direction out of the page. A loop of wire sits in the field and on the plane of the page (area vector of loop is out of page). The loop is much smaller than the extent of the field. The magnetic field starts to slowly change at a rate of -0.0001T/s. Looking down on the loop, which statement is correct? A. Magnetic flux out of page decreasing; anti-clockwise current induced in loop B....

6: A single-turn circular loop of wire rests flat on this page. A magnetic field is directed perpendicular to this page pointing outwards (towards you). When the magnetic field strength increases from 3.2 T to 6.5 T in 0.026 seconds, a 1 V emf is induced in the coil. a) Calculate the radius of the loop. b) State the direction of the induced current and briefly explain how you arrived at your answer.

A circle with a radius of 0.4 meters is placed in the x-y plane in a magnetic field directed in the -z direction. It is wound once and its resistance is 6 Ohms. The initial magnetic field is 0.6 Tesla. The magnetic field is then changed in 0.7 s and the average induced current is 0.03 amps running counter-clockwise. First, find the final magnetic field to needed to induce this average current. Then, the magnetic field (still in the -z...

Consider a rectangular "loop" of iron wire that is placed in a uniform magnetic field of magnitude 29T  pointing in the positive z -direction. At t=  4s , the ring is sitting in a magnetic field pointing in the positive z -direction whose magnitude changes linearly from 15T  at t=  4s  to 26T  at t=  9s . In which direction does the induced magnetic field coming from the induced current in the ring point at t=  6.5s ? In the positive x -direction. In the negative x -direction....

A magnetic field is passing through a loop of wire whose area is 0.014 m2. The direction of the magnetic field is parallel to the normal to the loop, and the magnitude of the field is increasing at the rate of 0.29 T/s. (a) Determine the magnitude of the emf induced in the loop. (b) Suppose the area of the loop can be enlarged or shrunk. If the magnetic field is increasing as in part (a), at what rate (in...

A physicist measures the magnetic field at the center of a loop of wire with N number of turns (not a solenoid) and current I flowing through it. They then triple the number of coils and half the radius of the coil while keeping the current the same. How does the magnetic field compare in the new situation, B2, compared to the first measurement, B1?
