Highlights of the Day
  • describe a magnetic field, and explain that it surrounds a magnet and exerts a force on other magnetic fields
  • Values :  Responsibility and Determination

Slide 3 - Tekstslide

Recall

Slide 4 - 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 8 - Tekstslide

Strongest
The magnetic field is strongest where the lines are closest together.

Slide 9 - Tekstslide

Slide 10 - 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 11 - 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.

Slide 13 - Tekstslide

Magnetic fields interacting
  • Two north poles repel.
  • Two south poles repel.
  • A north and a south pole attract.
