Electromagnetism
Term | Definition |
---|---|
Electrostatics | Any charge that is held in place on an object. *Occurs best on good insulators |
Static Electricity | The build up of charges in a place. *See electrostatics. |
Conduction | The separation of charges by direct contact. The separation of charges results in the object becoming either positively or negatively charged. |
Induction | The separation of charges without contact. Charges are separated within the object making the object temporarily charged. |
Coulomb's Law | The force from a charge is directly proportional to the strength of the charge and inversely proportional to the distance squared. Distance has a greater affect than strength. |
Electric Fields | The field surrounding a charge that shows the influence on surrounding objects by the charged object. |
Conductors | Objects that are good at passing charges through their system (Copper) |
Insulators | Objects that are not good at passing charges. They store charges well. (rubber) |
Electric Potential | Potential caused by the distance between attractive charges |
Magnetic Fields | A field that surrounds a magnetic substance that shows the influence of the magnetic field on magnetic substances |
Alternators/ Generators | A coil of wire surrounds a magnet that rotates creating an electric charge |
Electric Motors | A magnet that surrounds a coil of wire that turns an apparatus turning electric energy into mechanical energy. |
