Two coils A and B each having 1200 turns are placed near each other. When coil B is open circuited and coil A carries a current of 5A, the flux produced by coil A is 0.2Wb and 30% of this flux links with all the turns of coil B. The voltage induced in coil B on open-circuit when the current in the coil A is changing at a rate of 2 A/s is_

 

The figure shows the magnetic flux through a single-loop coil as a function of time. 

(a). What is the induced emf in the coil at t=0.050s?

(b). What is the induced emf in the coil at t=0.15s?

(c). What is the induced emf in the coil at t=0.50s?

Magnetic Flux and Induced EMF:

A coil has N turns enclosing an area of A. In a physics laboratory experiment, the coil is rotated during the time interval Δt from a position in which the plane of each turn is perpendicular to Earth's magnetic field to one in which the plane of each turn is parallel to the field. The magnitude of Earth's magnetic field at the lab location is B.

Part A- What is the magnitude Φ initial of the magnetic flux through the coil before it is rotated?

Part B- What is the magnitude Φ final of the magnetic flux through the coil after it is rotated?
