Chapter 12 - Magnetic Effects of Electric Current

1 / 15

The most important safety method used for protecting home appliances from short-circuiting or overloading is:

Use of stabilizers

Use of an electric meter

Earthing

Use of fuse

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

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 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.

3 / 15

Which rule is used to determine the direction of force when a current-carrying wire is placed in a strong magnetic field?

Right-hand thumb rule

Fleming's right-hand rule

Left-hand thumb rule

Fleming's left-hand rule

4 / 15

If the key in the arrangement is taken out (the circuit is made open) and magnetic field lines are drawn over the horizontal plane ABCD, the lines are

magnetic field around a straight conductor

Straight lines parallel to each other

Elliptical in shape

Concentric circles near point O but of elliptical shapes as we go away from it.

Concentric circles

5 / 15

Assertion (A): A stationary charged particle placed in a magnetic field experiences a force.

Reason (R): A stationary charged particle does not produce a magnetic field.

A is false but R is true

Both A and R are true and R is not the correct explanation of A

A is true but R is false

Both A and R are true and R is the correct explanation of A

6 / 15

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

Downwards

Clockwise

Counterclockwise

Upwards

7 / 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.

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

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.

8 / 15

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

Downwards

Counterclockwise

Upwards

Clockwise

9 / 15

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

found to increase from one end to the other

same at all points

minimum in the middle

more at the ends than at the centre

10 / 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

East-West

West-East

South-North

11 / 15

Why cannot two magnetic field lines intersect each other?

The compass needle would point toward two directions

It would create an electric field

The magnetic field would become unstable

It would violate the laws of electromagnetism

12 / 15

What do your fingers indicate when applying the Right-Hand Thumb Rule?

The magnitude of the current

The direction of the electric field

The resistance of the conductor

The direction of the magnetic field lines

13 / 15

Why is no magnetic field produced around a thin beam of moving neutrons?

Because neutrons are positively charged

Because neutrons are negatively charged

Because neutrons have zero mass

Because neutrons are electrically neutral

14 / 15

220 V, 50 Hz

420 V, 50 Hz

420 V, 100 Hz

220 V, 100 Hz

15 / 15
