Permanent and Induced Magnetism, Magnetic forces and Fields

• The poles of the magnet are where the magnetic forces are strongest.
• When two magnets are brought close to each other, they exert a force on each other.
• A small bar magnet that points in the direction of the Earth’s magnetic field.
• In the direction that a north pole would experience a force if placed in the field.
• From the north seeking pole to the south seeking pole of a magnet.
• A repulsive, non-contact force is exerted if two like poles of a magnet are brought near each other.
• The force between a magnet and a magnetic material is always attractive.
• An attractive, non-contact force is exerted if two unlike poles of a magnet are brought near each other.
• When an induced magnet is removed from a magnetic field, it loses most or all of its magnetism.
• Examples of magnetic materials include Iron, Steel, Cobalt, and Nickel.
• The strength of a magnetic field decreases as you move further away from the magnet producing it.
• A magnetic field is the region surrounding a magnet where another magnet or magnetic material experiences a non-contact force.
• A permanent magnet produces its own magnetic field.
• An induced magnet becomes magnetic when placed in a magnetic field.
• Induced magnetism always causes a force of attraction.
