A search coil having 2000 turns with area 1.5 cm2 is placed in a magnetic field of 0.60T. The coil is moved rapidly out of the field in a time of 0.2 second. Calculate the induced emf across the search coil.

A long solenoid consisting of 1.5×103 turns/m has an area of cross-section of 25 cm2. A coil C, consisting of 150 turns (Nc) is wound tightly around the centre of the solenoid. Calculate for a current of 3.0 A in the solenoid A long solenoid consisting of 1.5×103A long solenoid consisting of 1.5×103 turns/m has an area of cross-section of 25 cm2. A coil C, consisting of 150 turns (Nc) is wound tightly around the centre of the solenoid. Calculate for a current of 3.0 A in the solenoid

An alpha particle (the nucleus of helium atom) (with charge +2e) is accelerated and moves in a vacuum tube with kinetic energy = 10.00 MeV. On applying a transverse a uniform magnetic field of 1.851 T, it follows a circular trajectory of radius 24.60 cm. Obtain the mass of the alpha particle. [charge of electron = 1.62 × 10-19 C]

Example 10.4 A circular coil of conducting wire has 500 turns and an area 1.26 × 10−4 m2 is enclosed by the coil. A current 100μA is passed through the coil. Calculate the magnetic moment of the coil.

Example 10.3 Consider a square loop of wire loaded with a glass bulb of mass m hanging vertically, suspended in air with its one part in a uniform magnetic field B with its direction coming out of the plane of the paper . Due to the current I flowing through the loop, there is a magnetic force in upward direction. Calculate the current I in the loop for which the magnetic force would be exactly balanced by the force on mass m due to gravity.
