A 159 ‑turn circular coil of radius 3.49 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
10.9 Ω resistor to create a closed circuit. During a time interval
of 0.141 s, the magnetic field strength decreases uniformly from
0.539 T to zero. Find the energy ? in millijoules that is
dissipated in the resistor during this time interval.

A 37-turn circular coil of
radius 4.60 cm and resistance 1.00 Ω is placed
in a magnetic field directed perpendicular to the plane of the
coil. The magnitude of the magnetic field varies in time according
to the expression B = 0.010
0t + 0.040 0t2,
where B is in teslas and t is in
seconds. Calculate the induced emf in the coil
at t = 4.20 s.

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 0.23 V and a current of 2.4 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...

A 29-turn circular coil of radius 3.40 cm and resistance 1.00 Ω

0t2, where B is in teslas and
t is in seconds. Calculate the induced emf in the coil at
t = 4.60 s.

A 20-turn coil with a diameter of 6.00 cm is placed in a
constant, uniform magnetic field of 1.00 T directed perpendicular

increased at a uniform rate until it reaches 1.30 T at t = 10.0 s.
The field remains constant thereafter.

A coil 5.00 cm in radius, containing 250 turns, is
placed in a uniform magnetic field that varies with time according
to:

T/s5)t5. The coil is connected to
a 450 ohm resistor, and its plane is perpendicular to the magnetic

A circular wire loop of radius rr = 16 cmcm is immersed in a
uniform magnetic field BB = 0.375 TT with its plane normal to the
direction of the field.

−1.2×10−2 T/sT/s , at what rate should rr increase so
that the induced emf within the loop is zero?

A uniform magnetic field of strength 22.3 mT passes through the
