A 105‑turn circular coil of radius 2.41 cm and negligible
resistance is immersed in a uniform magnetic field that is
perpendicular to the plane of the coil. The coil is connected to a
14.7 Ω resistor to create a closed circuit. During a time interval
of 0.167 s, the magnetic field strength decreases uniformly from
0.481 T to zero. Find the energy, in millijoules, that is
dissipated in the resistor during this time interval.

A circular coil (830 turns, radius = 0.087 m) is rotating in a
uniform magnetic field. At t = 0 s, the normal to the coil is
perpendicular to the magnetic field. At t = 0.021 s, the normal
makes an angle of 45o with the field because the coil has made
one-eighth of a revolution. An average emf of magnitude 0.075 V is
induced in the coil. Find the magnitude of the magnetic field at
the location of the...

A magnetic field is perpendicular to the plane of a single-turn
circular coil. The magnitude of the field is changing, so that an
emf of 0.25 V and a current of 2.5 A are induced in the coil. The
wire is then re-formed into a single-turn square coil, which is
used in the same magnetic field (again perpendicular to the plane
of the coil and with a magnitude changing at the same rate). What
(a) emf and (b) current are...

To measure a magnetic field produced by an electromagnet, you
use a circular coil of radius 0.30 m with 25 loops (resistance of
0.30 O) that rests between the poles of the magnet and is connected
to an ammeter. While the current in the electromagnet is reduced to
zero in 1.5 sec, the ammeter in the coil shows a steady reading of
180 mA. Draw a picture of the experimental setup and determine
everything you can about the electromagnet.
