What is a solenoid ? Give the charcteristics of magnetic field resulting from solenoid.Write Answer of the given question.
Answers
''Solenoid is the iron bar which acts as a temporary magnet when the electric current flows through it. ''
Characteristics of the Solenoid are ⇒
1. The magnetic field created by it is very strong.
2. The direction of the magnetic field can be changed by changing the direction of the current.
3. It is used in electric bell and have the uses in Iron and magnetic industry.
Hope it helps.
1 A coil with many circular close turn of insulated copper wire is called solenoid
2 one end of such a solenoid behaved like the north and the other as a South Pole
3 the magnetic field due to current in the solenoid is similar to the bar magnet
4 the field always emerges out of the north Pole and always merge from South Pole
5 the field inside the solenoid is uniform
