Magnets have north and south poles that exert magnetic forces, attracting opposite poles and repelling like poles. Magnets create magnetic fields that can either attract or repel other magnets or iron entering the field. The Earth has its own magnetic field created by its molten iron core, which causes compasses to align with the magnetic north pole that is offset from true geographic north by around 9 degrees.

2. Magnetic Force
• Force a magnet exerts on anothermagnet, on
Iron, similar metals or on moveing charges
• Varies in distance.
• The 2 Magnetic Ploes are the strongest
regions. ( North & South)
• Opposite poles attract and Like magnetic poles
repel.

3. Magnitic fields
• The surraounding of a magnet and can exerts
magnetic force.
• It will either attract or repel another magnet
that enters the field.

4. Magnetosphere
• The compass aligns with
Earth’s magnetic fields.
• Geographic North Pole: 90º
Magnetic North Pole: 81º
• Magnetic declination is the
angel between the direction
to true north direction &
magnetic .
• Varies with location on Earth
