Question 1

In the magnetic core the electromotive forces (emf) induced in accordance with Faraday’s law of electromagnetic induction give rise to

Question 2

For high speed reading and storing of information in a computer, the core shall be of

Question 3

Soft magnetic materials should have

Question 4

At temperature above a limiting value, the energy of lattice vibrations, in a conductor, increases linearly with temperature so that resistivity increases linearly with temperature. In this region, this limiting value of temperature is called

Question 5

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:

Statement (I): Leakage reactance of the lower cage in a double-squirrel-cage motor is considerably higher than that of the upper cage.
Statement (II): The lower cage has high permeance for leakage flux.

Question 6

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:

Statement (I): Superconducting compounds and alloys must have components which are themselves superconducting.
Statement (II): Metals and compounds which are superconducting are rather bad conductors at ordinary temperatures.
