sLANT: eLECTROMAGNETS
electric current and magnetism
The magnetic field around a current-carrying wire forms closed circles.
the motion of charged particles creates a magnetic field
electric current flows through a wire
magnetic field is created around the wire carrying the current
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
made by wrapping a wire around a ferromagnetic core in a coil
the core greatly increases the magnetic field of current flowing through the wire
the more wrappings around the core, the greater the strength of the magnet
An insulated wire wrapped around a ferromagnetic core creates an electromagnet.
Properties of Electromagnets
they are temporary magnets
The strength f the magnet is directly proportional to
the number of coils
amount of electric current flowing
Reversing the electric current reverses the magnetic polarity
