|
the study of the nature, behavior, and uses of static electricity and related phenomena.
|
electrostatics
|
|
|
conducted many experiments with static electricity and what he called the "amber effect".
|
Sir William Gilbert
|
|
|
a property that allows them to attract and repel other charged particles by the electric force.
|
electric charge
|
|
|
the two opposite types of charges
|
positive and negative charge
|
|
|
the atom's positive and negative charges are precisely balanced and cancel each other out.
|
neutral
|
|
|
the simplest form of electricity
|
static electricity
|
|
|
the region surrounding a charged object in which objects are attracted or repelled by an electric force.
|
electric field
|
|
|
imaginary lines which indicate the direction and strength of the electric field.
|
lines of force
|
|
|
the unit of electric charge
|
coulomb
|
|
|
states that opposite charges attract each other but like charges repel each other.
|
law of electric charges
|
|
|
states that the strength of the attraction or repelsion between two charged objects is directly related to the strength of the charges and inversely related to the square of the distance between them
|
Coulomb's law of electric force
|
|
|
the most familiar way that electric charge is transferred.
|
contact
|
|
|
the process of diverting unwanted electrical charge directly into the earth.
|
grounding
|
|
|
the method of charge transfer produces electric charges at a distance.
|
induction
|
|
|
a simple device that uses the laws od\f electrostatics to detect small electric charges.
|
electroscope
|
|
|
a device that produces static electricity.
|
electrostatic generator
|
|
|
the most common electrostatic generator in use today.
|
Van de Graaff generator
|
|
|
a device for protecting buildings and other structures from lighining strikes.
|
lightning rod
|
|
|
an early device used to store an electric charge.
|
Leyden jar
|
|
|
a device used to store an electric charge.
|
capacitor
|
|
|
an object capable of attracting objects such as iron or steel by magnetic force.
|
magnet
|
|
|
the property of attracting objects by the magnetic force.
|
magnetism
|
|
|
the region surrounding a magnet in which other objects are affected by magnetism.
|
magnetic field
|
|
|
regions of concentrated magnetism.
|
poles
|
|
|
a north-seeking pole.
|
N pole
|
|
|
a south-seeking pole.
|
S pole
|
|
|
states that unlike poles attract each other, but like poles repel each other.
|
law of magnetic poles
|
|
|
states that the force between poles is directly related to the product of the pole strengths and inversely related to the square of the distance between the poles.
|
laaw of magnetic force
|
|
|
the extent to which a material can absorb or channel lines of magnetic force.
|
permeability
|
|
|
a navigational device consisting of a maget fee to swing horizontally so that it always point north.
|
magnetic compass
|
