A coil is suspended in a uniform magnetic field, with the plane of the coil parallel to the magnetic lines of force. When a current is passed through the coil it starts oscillating; it is very difficult to stop. But if an aluminium plate is placed near the coil, it stops. This is due to
A conducting circular loop is placed in a uniform magnetic field of 0.04T with its plane perpendicular to the magnetic field. The radius of the loop starts shrinking at 2mm/s. The induced emf in the loop when the radius is 2cm is:

A conducting circular loop is placed in a uniform magnetic field of 0.04T with its plane perpendicular to the magnetic field. The radius of the loop starts shrinking at 2mm s⁻1. The induced emf in the loop when the radius is 2cm is:
A conducting square loop is placed in a magnetic field \(B\) with its plane perpendicular to the field. The sides of the loop are shrinking at a constant rate \(\alpha\). The induced emf in the loop at an instant when its side is \(a\) is:
A coil of 10 turns and resistance \(20\,\Omega\) is connected in series with a battery of resistance \(30\,\Omega\). The coil is placed with its plane perpendicular to a uniform magnetic field of induction \(10^{-2}\,\text{T}\). If it is now turned through an angle of \(60^\circ\) about an axis in its plane, the charge induced in the coil is (Area of coil \(=10^{-2}\,\text{m}^2\)):
Eddy currents are produced when
Two coaxial solenoids are made by winding thin insulated wire over a pipe of cross-sectional area \( A = 10 \, \text{cm}^2 \) and length 20 cm. If one of the solenoids has 300 turns and the other 400 turns, their mutual inductance is
