Question

explani how magnetic field generated solenoid​

Answer 1

Explanation:

A solenoid is a long coil of wire. When a direct electric current is passed through it, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic fields caused by the current in each turn of the coil add together to make a stronger overall magnetic field.The strength of the magnetic field around a solenoid can be increased by:

• The strength of the magnetic field around a solenoid can be increased by:

• increasing the number of turns on the coil
• increasing the current
• placing an iron core inside the solenoid
• The use of an iron core makes the solenoid into an electromagnet which can be switched on and off.
