Question

The magnetic field lines inside a solenoid are in the form of parallel straight
lines. The reason for this is, the magnetic field insde the solenoid is :
A
very high
B. uniform
C.
Zero
D. produced by electricity
​

Answer 1

B. uniform

Hope uh understand

Answer 2

The magnetic field lines inside a solenoid are in the form of parallel straight  lines because the magnetic field inside the solenoid is uniform (Option b)

• When current is made to flow through a solenoid, a magnetic field is generated.
• The magnetic field lines inside the solenoid are parallel and equidistant suggesting that the magnetic field is uniform in nature.
• The magnetic field is dependent upon both the density of current and the number of turns in the solenoid.
