The magnetic field BB due to a small current loop (which we place at the origin) is called a magnetic dipole (Figure). Let ρ=(x2+y2+z2)1/2 For ρρlarge, B=curl(A), where

A = <−yρ3, xρ3, 0>

Let C be a horizontal circle of radius R=3with center (0, 0, 8). Use Stokes' Theorem to calculate the flux of B through C.

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....

(a) The magnetic field produced by the loop decreases further away from the loop. We can define an “effective distance” as how far along the z axis you must move from the center of the loop in order for the magnetic field to decrease to half its value at the center of the loop. What is the effective distance for the magnetic field of the loop? Compare the effective distance to the radius of the loop. (b) What data collected...

Helmholtz coils are a method developed to provide a uniform magnetic field in a small region. They are constructed by placing two identical wire loops parallel to each other, separated by a distance equal to their radii, as shown in the Figure. Assume that the two loops are also connected in parallel to a power supply, so that they produce the same field. (a) Find the length of a 28-gauge copper wire that will produce a 75 Ω coil. m...

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...
