Question

compare the magnetic field lines of force formed around a current careying solenoid with the magnetic field lines of force of a bar margnet

Answer 1

Objective:
To observe the magnetic field lines around current carrying solenoid.

Theory:
1.A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called a solenoid.
2.The pattern of the magnetic field lines around a current-carrying solenoid is illustrated.
3.The pattern of the field is similar to magnetic field around a bar magnet. One end of the solenoid behaves as a magnetic north pole, while the other behaves as the south pole.
4.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. That is, the field is uniform inside the solenoid.

Answer 2

hey mate
field lines around a solenoid are much more stronger than the speed lines around a bar magnet .
the reason behind this is that in solenoid the conductors are added you to the same direction for that's why the field lines offered by a solenoid are much more stronger than a bar magnet
