Play with your magnets!

ALL magnets have two poles NORTH seeking pole SOUTH seeking pole

Breaking a magnet produces two magnets!

Opposites attract!

Opposite poles attract and like poles repel

Magnetic materials

Magnetic materials Iron (steel), Cobalt and Nickel

Magnetic induction

Magnetic induction When a magnetic material is close to a magnet, it becomes a magnet itself We say it has induced magnetism magnet S N N S

Hard and Soft Magnetism

Soft Magnetism Pure iron is a soft magnetic material It is easy to magnetise but loses its magnetism easily before after N S S N N S N Not a magnet Iron nail

Hard Magnetism Steel is a hard magnetic material It is harder to magnetise, but keeps its magnetism (it is used to make magnets!) before after S N S N N S N N It’s a magnet! S Steel paper clip

I wonder if this is a magnetic field?

Magnetic field Magnets (and electric currents) produce magnetic fields around them. In the magnetic field, another magnet or magnetic material will experience a magnetic force.

Magnetic field lines We can represent the magnetic field around a magnet using field lines.

Magnetic field lines The arrows show the direction a compass needle would point at that point in the field.

Magnetic field lines The arrows show the direction a compass needle would point at that point in the field. The closer the field lines are, the stronger the magnetic force felt

Earth’s Magnetic Field Remember the North of a compass needle points to the geographic north pole (i.e. the geographic North pole is a magnetic south pole!) N S

Field around a bar magnet

Two bar magnets Strong uniform field

Two bar magnets no field!

That’s it!
