A square loop of side 50 cm is placed in a uniform magnetic field of 3·0 T acting perpendicular to the plane of the loop. If the loop is rotated through an angle of \(90^\circ\) in 0·3 s, the value of emf induced in the loop would be :
State Faraday’s law of electromagnetic induction.
A plane circular coil is rotated about its vertical diameter with a constant angular speed \(\omega\) in a uniform horizontal magnetic field. Initially the plane of the coil is parallel to the magnetic field. Draw the plot showing the variation of magnetic flux \(\phi\) linked with the coil as a function of \(\omega t\), where \(t\) represents the time elapsed.
A plane circular coil is rotated about its vertical diameter with a constant angular speed \(\omega\) in a uniform horizontal magnetic field. Initially the plane of the coil is parallel to the magnetic field. Draw the plot showing the variation of induced emf \(e\) in the coil as a function of \(\omega t\), where \(t\) represents the time elapsed.
Assertion (A) : Induced emf produced in a coil will be more when the magnetic flux linked with the coil is more. Reason (R) : Induced emf produced is directly proportional to the magnetic flux.
