Transferring
Charges
Charges
These particles move from one object to another thus causing a charge, whether it be positive or negative
Electrons
This is the study of nature, behavior and uses of static electricity and related phenomena.
Electrostatics
These imaginary lines are how we are able to "map" an electric field.
Lines of force
This is a simple device, first invented by this man, which can be used to detect an electric charge.
Electroscope
Sir William Gilbert
Define a magnetic field
The region surrounding a magnet in which other objects are affected by magnetism
Charging by this method is NOT temporary
Direct Contact
This gentleman used his famous kite experiment to show that lightning is a result of static electricity in the clouds.
Benjamin Franklin
Fill in the following blanks:
Lines of force are closest where the electric field is ____________, and are farther apart where the field is ____________.
strongest
weaker
This is a device that is used to store an electric charge. It is also a type of this. Explain how these devices discharge their stored electric charge.
Leyden Jar
Capacitor
They release their charge all at once
Sir William discovered that this object is itself a magnet.
The Earth
There are two types of charge. What are they?
Positive
Negative
Name the four methods are ways by which atoms are able to gain/lose electrons.
Heat
Friction
Chemical Action
Exposure to certain types of radiation
This is the unit used to measure electric charge
Coulomb
Electric charge always moves to this part of a charged object.
The outside
What is the angle of declination?
The angle that a compass needle deviates from true north.
Charge is transferred by these methods. Name the methods, identifying which of them is the most familiar way that electric charge is transferred.
2. Induction
The most familiar is direct contact
This is the simplest form of electricity.
Static Electricity
Define the Law of Electric Charges
It states that opposite charges attract each other, but like charges repel each other
This is called God's electrostatic generator
Thunderstorm
These two vast, doughnut-shaped belts of high-speed charged particles centered over the magnetic equator
Van Allen Radiation Belts
Charging by induction is usually temporary, however a permanent charge can be produced by combining induction with this.
Grounding
Define an electric field
The region/area surrounding a charged object in which other objects are attracted or repelled by an electric force
The equal amplitude of the charges would neutralize each other.
Explain how a lightning rod protects buildings and other structures from lightning strikes.
Lightning rods continuously drain electrons from the bottom of the cloud to the ground, thus preventing charges from getting strong enough to generate a lightning bolt.
What is an aurora?
What is the aurora called in the Northern Hemisphere? What is the aurora called in the Southern Hemisphere?
A colorful panorama of lights in the sky, caused by high-speed particles of the solar wind striking atoms of the Earth's upper atmosphere
Northern: Aurora Borealis
Southern: Aurora Australis
