Magnets and Magnetic Field Lines
Slide 1 - Tekstslide
Recall
Slide 2 - Tekstslide
Magnetic Fields
A
magnetic field
is the area around a magnet where the effects of the magnet can be detected.
EFFECTS:
Attraction or Repulsion

Slide 6 - Tekstslide
Strongest
The magnetic field is strongest where the lines are closest together.
Slide 7 - Tekstslide
Slide 8 - Tekstslide
Rules: Magnetic Field Lines
join opposite poles
have arrows that point N S
must not touch each other
must not cross each other
Slide 9 - Tekstslide
If one magnet is
stronger
than another, the magnetic field of the stronger magnet will be different in two ways.
All the field lines will be closer together.
The field lines will extend further away from the magnet.
