Magnets exert magnetic fields that flow from their north to south poles. Magnetic field lines indicate attraction when they curve towards each other. Motors use magnetic fields to convert electric energy into kinetic energy by forcing current-carrying wires to spin in loops. The aurora occurs when charged particles from the sun collide with atoms in Earth's atmosphere after spiraling along the planet's magnetic field lines towards the magnetic poles.

2. General Information
~ All magnets exert a magnetic force
~ This happens through a magnetic field
~ Magnetic fields surround all magnets
~ Magnetic field lines start at the north pole and
end on the south pole
~ Magnetic field lines are stronger when the field
lines are close to each other
~ If magnetic field lines curve towards each
other, they are showing attraction
~ Magnets have a north pole and a south pole

3. Magnets Move Currents
~ Electric appliances produce motion
~ Electric energy transforms into kinetic
energy
~ Current-carrying wires have an magnetic
field
~ Same magnetic field as a magnetic field
of a magnet
~ Current-carrying wires attract each other
like two magnets

4. Motors
~ A motor is any device that
converts electric energy into
kinetic energy
~ To keep it running, the current-
carrying wire changes into a
loop
~ Happens so the magnetic field
can force the wire to spin

5. Aurora
~ Appears when sun ejects many particles at once
~ Most of the particles are deflected by the magnetosphere of
the Earth
~ However some of these particles from the sun produce other
charged particles in Earth’s outer atmosphere
~ The charged particles then spiral along Earth’s magnetic
field lines toward it’s magnetic poles
~ They collide with atoms in the atmosphere
~ This causes the atoms to emit light
