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 0.61 V and a current of 3.2 A are induced in the coil. The wire is the 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 and current are induced in...
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 0.26 V and a current of 4.9 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 141 turn circular coil of radius 2.61 cm is immersed in a uniform magnetic field that is perpendicular to the plane of the coil.

A 23-turn circular coil of radius 3.00 cm and resistance 1.00 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 Ot + 0.040 ot, where B is in teslas and t is in seconds. Calculate the induced emf in the coil at t = 5.20 s. 2.77 If the flux is changing as a function of time, how do...
