Question

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 to the plane of the coil. Beginning at time t = 0 s, the field is increased at a uniform rate until it reaches 1.30 T at t = 10.0 s. The field remains constant thereafter.

1) What is the magnitude of the induced emf in the coil at t < 0 s?

2) What is the magnitude of the induced emf in the coil at t = 5.00 s?

3) What is the magnitude of the induced emf in the coil at t > 10.0 s?

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

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...
