Solenoid

A solenoid is a coil of wire that acts like a magnet when an electric current flows through it. It creates a magnetic field, similar to the one around a bar magnet, but it's controlled by electricity. The more loops in the coil and the stronger the current, the stronger the magnetic field becomes. Solenoids are u...

A solenoid is a coil of wire that produces a magnetic field when electric current flows through it.

When current flows through the coil, it turns the solenoid into an electromagnet with north and south poles.

The magnetic field inside a solenoid is strong and nearly uniform, similar to the field of a bar magnet.
