Magnetic Fields & Induction

Front

Magnetic Attraction

Back

Opposite poles come together, North to South

Front

Magnetic poles

Back

Where a magnetic field around a magnet is strongest,

Where the field lines are most dense

Front

Domains

Back

areas of a substance where the electrons spins in a similar direction

Front

Electromagnetic induction

Back

When a magnetic field is moved near a wire and a creates a current.

Also the creation of a magnetic field around a moving current.

Front

Ways to increase electromagnetic induced voltage

Back

More loops in the coil,

Faster moving magnets,

Closer distance between magnet and wire coil.

Front

Transformer

Back

Device made of two coils of wire that induce avoltage between them, increasing or decreasing the volts.

Front

Ammeters & Galvanometers

Back

Detect current

Front

Motors

Back

Turn electrical energy to mechanical energy

Front

Device that creates electricity from magnetism

Back

A generator

Front

Electromagnet

Back

A magnet made of wire and a voltage source.
