Magnetism and electromagnetism • The motor effect

Key concepts

What you'll likely be quizzed about

  • A solenoid is a long coil of wire, typically wound in a cylindrical shape.
  • When electric current flows through the wire, it generates a magnetic field inside the coil, resembling a bar magnet's field.

What effect does increasing the current have on a solenoid's magnetic field?

Click to reveal answer

Increasing the current through a solenoid intensifies the magnetic field, enhancing its strength.

Key notes

Important points to keep in mind

Solenoids produce stronger fields than straight wires.

More turns in a coil increase magnetic field strength.

Current direction defines magnetic field orientation.

Solenoids can act as electromagnets.

Core materials significantly affect magnetic strength.
