8. The current produced during electromagnetic induction is known as
9. Does electromagnetism work under water?
10. Who discovered the relation between electricity and magnetism?
11. A solenoid carrying current behaves like an electromagnet. To determine poles of the solenoid which rule is helpful?
12. We are rotating a 1 m long metallic rod with an angular frequency of 400 red s^-1 with an axis normal to the rod passing through its one end. And on to the other end of the rod, it is connected with a circular metallic ring. There exist a uniform magnetic field of 0.5 T which is parallel to the axis everywhere. Find out the emf induced between the centre and the ring.
13. A long solenoid with 15 turns per cm has a small loop of area 2.0 cm^2 placed inside the solenoid normal to its axis. If the current carried by the solenoid changes steadily from 2.0 A to 4.0 A in 0.1 s, what is the induced emf in the loop while the current is changing?
14. The induced voltage across a coil with 250 turns that is located in a magnetic field that is changing at a rate of 8 Wb/s is
15. When the current through the coil of an electromagnet reverses, the
