eSaral Class 12 Magnetic Field of a Solenoid 🚀 Checkout eSaral Courses Magnetic Field of a Solenoid A solenoid is a long cylindrical helix. It is made by winding closely a large number of turns of insulated copper wire over a tube of cardboard or china-clay. When an electric current is passed through the solenoid, a magnetic field is produced around and within the solenoid. The figure shows the lines of force of the magnetic field due to a solenoid. The lines of force inside the solenoid are nea...
