Magnetism MCQ - Electrician (Set-1) with Answers

21) What type of electrical current effect will be produced when the current is passed through the spirally wound coil ?

Answer is:

Magnetic effect

22) The unit of reluctance is :

Answer is:

ampere turns/weber

Explanation:

Reluctance is magnetomotive force per unit flux,
So unit of reluctance = unit of MMF / unit of magnetic flux = A/Wb. = Ampere turns / Weber

23) The resistance in electrical circuit is analogous to magnetic circuit is :

Answer is:

reluctance

24) Which magnetic term is the analogous (similarity) to the electrical term of current ?

Answer is:

Flux

25) What is the unit of permeability ?

Answer is:

no unit
