This area exerts forces on other objects without touching them
Force Field
The place on a magnet that has the strongest force of a magnetic field
North and South poles
The two types of charges in an electrostatic field
Positive and Negative
The Man who discovered gravity
Sir Issac Newton
An electromagnet must have this flowing through it
Eclectic current
The loss of static electricity as electric charge from one object to another
Static Discharge
This is an area of force around a charged object that may exert force on other charged objects
Electrostatic Field
How the Earth's magnetic field is powered.
The Earths outer core
The buildup of charges on an object
Static Electricity
NO! Weight...That's not a controlling factor of gravitational field strength. But this is
Mass
A piece of metal like iron for the coil to wrap around
Core
The attraction or repulsion of electrons by an external electric field which causes electrons to move within their own atoms
Polarization
Protects Earth from solar winds
Magnetic Field
A navigation device that works with the Earth's magnetic field?
A Compass
When two electrons get too close to each other they do this
Repel
They say that distance makes the heart grow fonder, but it also does this to gravitational strength as objects moves further from each other
Weakens
Supplies the coil with electric current
Power source
Redistributing charge of an object using another objects electric field.
Induction
An area of force created around any body with mass
Gravitational Field
When north and south poles of a magnet are pushed together.
They Attract
Mr. Smith demonstrated he could be this, as well as a magician.
Conductor
A measurement of the force of gravity
Weight
Michael Faraday discovered this
Electromagnetic induction
Transfer of charge by rubbing two surfaces together.
Friction
Has a positive and negative charge
Electrostatic Field
A natural magnetic mineral that tells Geologist that Earth's magnetic field once reversed
Magnetite
The force between two charged objects
Electric force
Gravity from this body causes most places on Earth to have two high tides a day.
The moon
This type of metal is commonly used as the core for an electromagnet to increase its magnetic field
Iron
Transfer of charge that takes place when two objects touch.
Conduction
