Question

the magnetic field lines inside a solenoid are in the form of parallel straight lines, the reason for this is, the magnetic field inside the solenoid is

a)very high
b) uniform
c) 0
d)produced by electricity​

Answer 1

★Answer:-

(b) uniform

★Explaination:-

Before finding the answer, let's understand what is a solenoid!

Solenoid is a coil of insulated copper wire wound around an iron ore it is called solenoid.

Now move on to the question!

The magnetic field lines inside a solenoid are in form of parellel straight lines, the reason for this is, the magnetic field lines inside a solenoid is uniform at each point.

Reason for above discussion!

Solenoid acts as a bar magnet and we know that field lines moved from north to south pole in a bar magnet. It goes uniformally inside a solenoid from North to South pole, field lines doesn't intersect each other and goes parellel along the axis.

★Additional Information:-

How to increase Magnetic field lines inside a solenoid?

-Magnetic field lines inside a solenoid can be increased by following ways:

• By increasing the number of turns of coil.

• By increasing the current in the coil.

• By placing a magnetic material such as soft iron core in between coil.

• By increasing area of coil.

Answer 2

Answer:

The magnetic field lines inside a solenoid are in the form of parallel straight lines, the reason for this is, the magnetic field inside the solenoid is uniform i.e.option(b).

Explanation:

First, let's understand some properties of solenoids,

• A magnetic field is created when a current is made to flow through a solenoid.

• The parallel and even spacing of the magnetic field lines within the solenoid suggests that the magnetic field is of a uniform nature.

• Both the density of the current and the number of solenoids turn to affect the magnetic field.
• Because the magnetic field inside a solenoid is uniform, the lines that make up its magnetic field are parallel straight lines.

The magnetic field lines inside a solenoid are in the form of parallel straight lines, the reason for this is, that the magnetic field inside the solenoid is uniform i.e.option(b).
