Electromagnetic Induction

Question:

Magnetic flux of 12 μWb is linked with a coil and a current of 0.2A passes through it. What will be the self inductance of the coil?

Options:

6x 10-5 H

6.7x 10-5 H

6mH

6x 10-6 H

Correct Answer:

6x 10-5 H

Explanation:

Magnetic flux associated with a coil : Φ =  Li

                              Self inductance : L =  Φ/i

                                                       = (12x10-6)Wb/ 0.2A

                                                       = 6x 10-5 H
