A cycle wheel of radius 0.5 m is rotated with constant angular velocity of 10 rad/sec in a region of magnetic field of 0.1 T which is perpendicular to the plane of the wheel the emf generated between its centre and the rim is…

A coil of resistance 400 Ω is placed in a magnetic field. If the magnetic flux ϕ (Wb) linked with the coil varies with time t (sec) as ϕ = 50t2 +4 The current in the coil at t= 2 sec is A long solenoid of diameter 0.1 m has 2×10^4 turns per metre.At the centre of the solenoid
