Report | Ankush asks : Area of cross-section of a solenoid is 1.2 x 10-3 m, its length is 0.3 m. It has 2000 turns over it. A coil having 300 turns is wound on its central part. If 2 ampere current changes its direction in 0.1 second then, what is the induced e.m.f.? |
Report | Veer asks : The magnetic flux linked with coil, in web is given by the equation, φ = 5t2 + 3t + 16. The induced emf in the coil in the fourth second is : |
