Faraday’s law states that the induced emf in a coil is directly proportional to the(1 Point)rate of change in the magnetic field.rate of change in the magnetic flux.rate of change in the electric field.rate of change in the electric flux.

According to Faraday's law, the magnitude of the induced electromotive force (emf) in a closed loop is proportional to the rate of change of:Select one:a. Electric Fieldb. Electric Chargec. Magnetic Fieldd. Magnetic Flux

Two coils are placed near each other, and one is on top of the other one. The magnetic flux through thetop coil changes due to a varying current in the coil.(a) Suppose the magnetic flux through the top coil increases at a uniform rate of 0.3 Wb/s, what is theinduced emf in the bottom coil? Is it constant with time?(b) Suppose the magnetic flux through the top coil decreases at a varying rate of 0.5t Wb/s, what is theinduced emf in the bottom coil? Is it constant with time? What happens to the direction of thecurrent in the bottom coil, as compared with part a)?(c) Suppose that the current described in part a) is in the bottom coil rather than the top one. What isthe induced emf in the top coil?

n a coil of resistance 100  a current is induced by changing the magneticflux through it. The variation of current with time is as shown in the figure. Themagnitude of change in flux through coil is(a) 200 Wb (b) 275 Wb (c) 225 Wb (d) 250 Wb

State  Faraday's law of magnetic induction.

An increasing magnetic field is 45.0° clockwise from the vertical axis, and increases from 0.500 T to 0.6 T in 4.30 s. There is a coil at rest whose axis is along the vertical and it has 100 turns and a diameter of 6.00 cm. What is the induced emf?
