Helmholtz coils. Sometimes experimenters need to produce a magnetic field that is constant over some region of space, without wrapping a long straight solenoid around the experiment. Here’s a good way to do that. a. Show that the magnetic field a distance z along the axis of a circular conducting loop with radius a and current I is

17.1) Helmholtz coils The magnetic field on the axis of a circular loop of wire is not very uniform (in fact, we showed that the field strength decreases as 1/r3 ). But, with two such coils, one can produce a relatively uniform field in a small neighborhood. Consider two parallel circular coils of radius a, centered on the y-axis. One coil is in the y = 0 plane, and the other is in the y = d plane. Assume that...

Helmholtz coils are frequently used in experiments because they create a uniform magnetic field about their axial direction. For example, they are traditionally used in the experiment for the measurement of the charge to mass ratio of the electron. Helmholtz coils are two coils separated by a distance equal to their radius and also carry equal currents in the same direction, as shown in the figure on the right. Suppose the radius of the coils is 12.00 cm, each coil...

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...

If you pass a current through a wire, you can create a magnetic field. In this class we examine the field from three specific configurations: an infinitely-long straight wire, a compact loop of wire (possibly with multiple turns, a coil), or an infinitely long solenoid (think of an infinitely-long cylinder of loops made by wrapping a single wire). See the text for an extended description of all three geometries. Here’s the challenge: there are three slightly different formulas used to...

(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...

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...
