perpendicular

all of the above

parallel

same

2 / 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

3 / 15

6 / 15

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

7 / 15

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

same at all points

minimum in the middle

found to increase from one end to the other

more at the ends than at the centre

8 / 15

What is the conventional direction of magnetic field lines?

From east to west

From west to east

From south pole to north pole

From north pole to south pole

9 / 15

Why cannot two magnetic field lines intersect each other?

It would violate the laws of electromagnetism

The magnetic field would become unstable

The compass needle would point toward two directions

It would create an electric field

10 / 15

Counterclockwise

Clockwise

Upwards

Downwards

11 / 15

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

12 / 15

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

The resistance of the conductor

The magnitude of the current

The direction of the electric field

The direction of the magnetic field lines

13 / 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 true but R is false

A is false but R is true

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

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

14 / 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 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.

15 / 15

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

Because neutrons are electrically neutral

Because neutrons have zero mass

Because neutrons are negatively charged

Because neutrons are positively charged
