Question

2. A circular coil with 30 turns of wire has a diameter of 2.00 cm. The total resistance of the coil is 0.350 Ω. An applied uniform magnetic field is directed upward, perpendicular to the plane of the coil.

a) If the magnetic field changes linearly from 0.000 T to 0.800 T in 0.500 s, what is the induced emf in the coil while the field is changing?

b) What is the magnitude and direction (CW or CCW when looked at from above the coil) of the induced current in the coil while the magnetic field is changing?

A flat circular coil with 96 turns, a radius of 3.72 10-2 m, and
a resistance of 0.432 Ω is exposed to an external magnetic field
that is directed perpendicular to the plane of the coil. The
magnitude of the external magnetic field is changing at a rate of
ΔB/Δt = 0.837 T/s, thereby inducing a current in the coil. Find the
magnitude of the magnetic field at the center of the coil that is
produced by the induced current.

A flat, circular coil has 40 turns of radius 3.6 cm. At t=0 an
external magnetic field perpendicular to the plane of the coil has
a value of 0.32 T and is decreasing linearly with time. At t = 0,
the induced emf is 65 mV. How long does it take for the field to
reach zero?

A 29-turn circular coil of radius 3.40 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 = 4.60 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...

9. 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 0.77 V and a current of 2.7 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 emf is induced in the...

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 flip coil consist of a circular coil of 2cm diameter and 100
turns. It is situated in magnetic field of 0.050T with field at an
angle of 60o with plane of coil. What emf will be
