The Motor Principle An electromagnet that interacts with another magnet can create a directed force (as discovered by Faraday as the first motor).
Magnetism. Force Attractions exist between some metals Force is most concentrated at the ends of the metal object Ends are called Poles (North and South)
Magnets and Magnetic Fields
Magnetism. Magnets Any material that creates a magnetic field Any material that creates a magnetic field –Some materials can be made into permanent magnets.

 An Introduction to Magnetism. Permanent Magnets Have north “poles” and south “poles” Like poles repel, opposites attract Most, but not all, metals are.
Magnetism. Magnets Magnets: -opposite ends attract -like ends repel -most metals attract to magnets -we utilize magnetism and make compasses from Earth’s.
