Magnetism

Magnetism is generated by moving

• protons

• electrons

• neutrons

• elements

What do the lines around this magnet represent?

• North Pole

• South Pole

• Magnetic Declination

• Magnetic Field

As the distance between two magnets increases (they get farther apart), the force between them:

• Increases
• Decreases
• Stays the Same

• Both halves get only a South Pole
• Both halves get a North pole and a South Pole

What is responsible for the Magnetic Field around Earth?
