Question
Match the following with the correct response.
(1) Magnetic field inside the solenoid (A) Small bar magnet capable of rotating freely
(2) Compass needle (B) Temporary magnet
(3) Solenoid with soft iron core (C) Uniform
- 1-C, 2-B, 3-A
- 1-C, 2-A, 3-B
- 1-B, 2-A, 3-C
- 1-A, 2-C, 3-B
Hint:
The wires in solenoid are parallel which allows uniform magnetic field and and is directed along the axis of the solenoid
Needle has the tendency to align itself to the magnetic line of force
Solenoid is an electromagnet
The correct answer is: 1-C, 2-A, 3-B
- Magnetic fields inside the solenoid is uniform because magnitude remain equal and direction of magnetic field remain same at each point of solenoid. The wires in solenoid are parallel which allows uniform magnetic field and and is directed along the axis of the solenoid
- The magnetic line of force of earth emerges from the north pole and ends up to the south pole and it makes a loop just like in a bar magnet the magnetic line of force emerges from north and enters to the south pole. So the needle has the tendency to align itself to the magnetic line of force.
-
The bar magnet is a permanent magnet whereas a solenoid is an electromagnet ie, it acts as a magnet only when an electric current is passed through.
1-C, 2-B, 3-A
