MAGENTS
SCIENCE TASK
what is a magnet?
A magnet is a piece of iron or other material which has its component atoms.
what can a magnet do?
A magnet attracts other metal objects to it.
can magnetism be stopped?
No, magnetic fields cannot be stopped.
can magnets be made? if so, how?
one way of making a magnet is getting a small piece of metal (earring, paperclip etc..), and rubbing it against a magnet.
what is a magnetic field?
A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
how can electricity make a magnet?
A normal, straight wire creates a magnetic field that affects a compass needle, A coil of wire around a piece of metal creates a real electromagnet .
how can we explain how electromagnets work?
By running electric current through a wire, you can create a magnetic field.
An electromagnet starts with a battery (or some other source of power) and a wire. What a battery produces is electrons.

Give examples of uses in the real world.
Electromagnets are used in everyday life in a generator or alternator in a car,
small motors around the workshop of a house, kitchen appliances and giant electrical generators.
