Problem 24.4
For a particular scientific experiment, it is important to be
completely isolated from any magnetic field, including the earth's
field. The earth's field is approximately 50 ?T,
but at any particular location it may be a bit more or less than
this. A 1.00-m-diameter current loop with 200 turns of wire is
adjusted to carry a current of 0.219A ; at this current, the coil's
field at the center is exactly equal to the earth's field in
magnitude...

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 ration of the electron. Helmholts
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. Supposed the radius of the coil is 15.00
cm, each coil...

The orientation of small satellites is often controlled using torque from current-carrying coils in Earth's magnetic field. Suppose a multiturn coil has a cross-sectional area of 6.96 ✕ 10−4 m2, dissipates 0.300 W of electrical power from a 5.50 V power supply, and provides a magnetic moment of magnitude 0.0400 A · m2. (a) Find the coil current I (in A). A (b) Calculate the number of turns in the coil. turns (c) Calculate the maximum magnitude of torque (in...
