6: A single-turn circular loop of wire rests flat on this page. A magnetic field is directed perpendicular to this page pointing outwards (towards you). When the magnetic field strength increases from 3.2 T to 6.5 T in 0.026 seconds, a 1 V emf is induced in the coil.

a) Calculate the radius of the loop.

b) State the direction of the induced current and briefly explain how you arrived at your answer.

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 magnetic field, strength 3T, has a direction out of the page. A loop of wire sits in the field and on the plane of the page (area vector of loop is out of page). The loop is much smaller than the extent of the field. The magnetic field starts to slowly change at a rate of -0.0001T/s. Looking down on the loop, which statement is correct? A. Magnetic flux out of page decreasing; anti-clockwise current induced in loop B....

PLEASE SHOW ALL WORK! A 50-turn coil of wire lies in a magnetic field directed into the page. The coil has an initial area of 0.325 cm^2 a) If the magnetic field strength is 1.50 T, what is the magnetic flux through the coil? b) Suppose we now crush the coil so that its area is very small; i.e., effectively zero. If this process takes 0.175 s, what is the average induced emf?
