Review Quiz results

SLANT: Electromagnets

electric current and magnetism

The magnetic field around a current-carrying wire forms closed circles.

The magnetic field around a current-carrying wire forms closed circles.

  1. the motion of charged particles creates a magnetic field

  2. electric current flows through a wire

  3. magnetic field is created around the wire carrying the current

  4. increasing the flow of electricity increases the strength of the magnetic field.

Permanent magnets can exert a force on a current carrying wire (demonstration).

Electromagnets

  1. made by wrapping a wire around a ferromagnetic core in a coil

  2. the core greatly increases the magnetic field of current flowing through the wire

  3. the more wrappings around the core, the greater the strength of the magnet

An insulated wire wrapped around a ferromagnetic core creates an electromagnet.

An insulated wire wrapped around a ferromagnetic core creates an electromagnet.

Properties of Electromagnets

  1. they are temporary magnets

  2. The strength f the magnet is directly proportional to

  3. the number of coils

  4. amount of electric current flowing

  5. Reversing the electric current reverses the magnetic polarity
