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) The magnetic field is a certain region varies with time given by B(t) =30e^ -2t in Tesla. A 10cm * 15cm rectangular coil whose plane is perpendicular to the direction of the magnetic is placed in this field, find the magnetic flux as a function of time flux(t). b) A coil consists of 200 turns of wire. Each turn is a square of side d=18cm, and a uniform magnetic field directed perpendicular to the plane of the coil is...

Just part B and C
In-class problem A coil consists of 200 turns of wire. Each turn is a square of side d = 18 cm, and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. The figure shows the behavior of the magnitude of the magnetic field with time. From 1=0 to 1=0.80 s, the field changes linearly from 0 to 0.50 T. After 1 = 0.80 s, the magnitude of the field...

14- please help me with my physics HW
Wire is wound on a square frame, 30 cm by 30 cm, to form a coil of 7 turns. The frame is mounted on a horizontal shaft through its centre (perpendicular to the plane of the diagram), as shown in the figure. The coil is in clockwise rotation, with a period of 0.060 s. A uniform, horizontal, magnetic field of magnitude 0.40 T is present. At a given instant, the plane of...
