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

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

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.

14 / 15

In our houses we receive AC electric power of ______ with a frequency of ______.

220 V, 50 Hz

420 V, 100 Hz

420 V, 50 Hz

220 V, 100 Hz

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

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 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.
