Magnets & magnetic fields
Download as PPTX, PDF2 likes10,852 views
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.

- 1. Magnets & Magnetic Fields Priscy Laraury & Lucy Artigas
- 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. Iron Fields Revel the field lines
- 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
