ATOMS
What contains the protons and neutrons
the nucleus
A charge imbalance that results in the build up of excess electric charge on an object.
Static Electricity
area surrounding charged particles/objects within which a force can be exerted on other charged particles/objects.
Electric Field
property of some materials that allows them to give off an attractive or repulsive force
Magnetism
closed path through which electrons can flow.
Circuit
What is the charge of protons?
positive
Opposite forces when in close proximity to each other will?
Attract
materials that allow e- to flow easily; readily conduct electric charge.
Conductors
a material that gives off an external magnetic field, making it possible to apply a force over a distance
a magnet
current has only one path to travel through
Series Circuit
What is the charge of electrons?
negative
Same charges when in close proximity to each other will?
Repel
materials that block the flow of e- through them.
Insulators
Magentic force is strongest at...
the poles
contains more than one path for current to travel through.
Parallel circuit
Where are the electrons located?
the electron cloud
What direction does current flow from a battery?
Negative to positive
transfer of electrons through direct contact between objects.
Conduction
When all the atoms magnetic field are aligned it creates...
A magnetic element
Apparatus that opens and closes a circuit
A switch
An atom with a net charge
Ion
Says charge can't be created or destroyed
Law of Conservation of Charge
tool used to detect the presence and magnitude of an electric charge.
Electroscope
phenomenon where objects placed in a strong magnetic field become magnetized due to the poles within their atoms aligning
Ferromagnetism
The unit of measure for current
Amps
