Magnetic Flux: Practice Problem & Solution

Some magnetic flux is changed from a coil of resistance 10 ohm. As a result an induced current is developed in it, which varies with time as shown in figure. The magnitude of change in flux through the coil in webers is: Magnetic Flux diagram: Some magnetic flux is changed from a coil

1. Two coils are at fixed locations. When coil 1 has no current and the current in coil 2 increases at the rate 15.0 A/s the emf in coil 1 in 25.0 mV, when coil 2 has no current and coil 1 has a current of 3.6 A, the flux linkage in coil 2 is:
2. Assertion (A): A changing magnetic flux induces an electric field. Reason (R): An inductor always tends to keep the flux constant.  
3. A flux of \(10^{-3}\text{ Wb}\) passes through a strip having an area \(A = 0.02\text{ m}^2\). The plane of the strip is at an angle of \(60^\circ\) to the direction of a uniform field \(B\). The value of \(B\) is:
4. Assertion (A): Magnetic flux is a vector quantity. Reason (R): Value of magnetic flux cannot be negative.
