A coil of 100 turns, 5cm² area is placed in external magnetic field of 0.2 Tesla (S.I.) in such a way that it makes an angle 30° with the field direction. Calculate magnetic flux through the coil (in weber).

A coil of N turns, A area is placed in uniform transverse magnetic field B. If it is turn through 180º about its one of the diameter in 2 seconds. Find rate of change of magnetic flux through the coil.

A square cube of side ’a’ is placed in uniform magnetic field B’. Find magnetic flux through each face of the cube.

The magnetic field perpendicular to the plane of a loop of area 0.1 m² is 0.2 T. Calculate the magnetic flux through the loop.

The magnetic field in a certain region is given by $\overrightarrow{B}=(4\hat{i}-\hat{k})$ tesla. How much magnetic flux passes through the loop of area 0.1m² in this region if the loop lies flat in xy plane ?

A solenoid 4cm in diameter and 20cm in length has 250 turns and carries a current of 15A. Calculate the flux through the surface of a disc of 10cm radius that is positioned perpendicular to and centered on the axis of the solenoid.
