Question

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

Answer 1

Answer:

A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called a solenoid. ... The field lines inside the solenoid are in the form of parallel straight lines. This indicates that the magnetic field is the same at all points inside the solenoid

Answer 2

Magnetic field of a solenoid carrying current is similar to bar magnet as it also has the poles on either side and field lines(magnetic) are curve outside and straight inside the solenoid.

The lines of magnetic field from a bar magnet form closed lines. By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet. Permanent magnets can be made from ferromagnetic materials.

Lines of Force from a Bar Magnets Magnetic Field

The general direction for the magnetic flux flow is from the North ( N ) to the South ( S ) pole. In addition, these magnetic lines form closed loops that leave at the north pole of the magnet and enter at the south pole. Magnetic poles are always in pairs
