Magnetic Field due to a Solenoid class 10 | cbse24

The solenoid is a long coil containing a large number of close turns of insulated copper wire. The magnetic field produced by a current-carrying solenoid is similar to the magnetic field produced by a bar magnet.


The lines of magnetic field pass through the solenoid and return to the end. The magnetic field lines inside the solenoid are in the form of parallel straight lines.

This indicates that the strength of the magnetic field is the same at all the point inside the solenoid. If the strength of magnetic fields is just the same in a system, it is said to be a uniform magnetic field. Thus, the magnetic field is uniform inside a current-carrying solenoid.

By clock face rule where the current is entering the solenoid that is the South Pole and where the current is out that is the North Pole.

The strength of the magnetic field produced by a current-carrying solenoid depends on

1:-The number of turns in the Solenoid: Larger the number of turns in the solenoid, greater will be the magnetic produced

2:The strength of the current in the Solenoid:-the Larger the current passed through the solenoid, the stronger will be the magnetic field Produced

3:-The nature of “Core Material” used in making the Solenoid: The use of the soft iron rod as core in a solenoid produced the strongest magnetism.
