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...

1. A 85 turn elastic circular coil of wire initially has a radius of 74.2 cm and is immersed in a uniform magnetic field with a strength of 0.495 T. At t 0, the coil is released and begins decreasing in radius at a constant rate of 7.22 cm/s. While it contracts, the number of turns does not change. a) Write the magnetic flux through a single turn of the coil as a function of time. (Hint: What causes 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 0.26 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...
