B

`pi//2`

C

`pi//4`

D

`pi//6`

Text Solution

To induce an e.m.f. in a coil, the linking magnetic flux

Faraday's second law of EMI says that the magnitude of e.m.f. induced in a cuicuit is directly proportional to the rate of change of magnetic flux linked with circuit, i.e., e prop (d phi)/(dt) . It means if the magnetic flux linked with a circuit changes at a faster rate, the induced e.m.f. is larger and vice-versa. Read the above passage and answer the following question : (i) Coil A is held in a very strong magnetic field and coil B is held in a weak magnetic field. In which coil do you expect larger induced e.m.f. ? (ii) A coil is moved in a uniform magnetic field. When do you expect induced e.m.f. in the coil ? (iii) What values of life do you learn from Faraday's second law of EMI ?

Identify the correct statement I. The flux can be altered by changing the shape of a coil in a magnetic field or rotating coil in a magnetic field such that the angle between B and A changes. II. By changing the shape of a coil or the angle between B and A, an emf is induced in the coil. Which of the above statement(s) is/are correct?
