Chapter 12 - Magnetic Effects of Electric Current

1 / 15

Why cannot two magnetic field lines intersect each other?

The magnetic field would become unstable

The compass needle would point toward two directions

It would violate the laws of electromagnetism

It would create an electric field

2 / 15

What is the direction of the magnetic field at a point directly above a horizontal power line carrying current from west to east?

North-South

West-East

East-West

South-North

3 / 15

A positively charged particle (alpha-particle) projected towards the west is deflected towards the north by a magnetic field. The direction of the magnetic field is:

Towards east

Upward

Downward

Towards south

4 / 15

What is the direction of the magnetic field lines if the current flows away from you?

Downwards

Clockwise

Counterclockwise

Upwards

5 / 15

The strength of magnetic field inside a long current carrying straight solenoid is

same at all points

minimum in the middle

more at the ends than at the centre

found to increase from one end to the other

6 / 15

Which circuit shows the correct and safe positions for the fuse and the switch?

magnetic effects of electric current important questions and answers

7 / 15

For a current in a long straight solenoid N- and S-poles are created at the two ends. Among the following statements, the incorrect statement is:

The strong magnetic field produced inside the solenoid can be used to magnetize a piece of a magnetic material like soft iron when placed inside the coil.

The N- and S-poles exchange position when the direction of current through the solenoid is reversed.

The field lines inside the solenoid are in the form of straight lines which indicates that the magnetic field is the same at all points inside the solenoid.

The pattern of the magnetic field associated with the solenoid is different from the pattern of the magnetic field around a bar magnet.

8 / 15

Choose the incorrect statement from the following regarding magnetic lines of field:

Relative strength of the magnetic field is shown by the degree of closeness of the field lines.

Magnetic field lines are closed curves.

The direction of the magnetic field at a point is taken to be the direction in which the north pole of a magnetic compass needle points.

If magnetic field lines are parallel and equidistant, they represent zero field strength.
