Magnetism and Electricity Flashcards
Energy
Motion or interaction of molecules, the ability to do work
Electrons
Subatomic particles that have a negative charge
Magnetism
A force that can repel or attract objects that contain a magnetic material inside of them.
- caused by electrical charges
- Magnetic materials: cobalt, nickel, iron, magnetite
Magnetic Field
A force that can attract or repel objects that contain a magnetic material inside them.
*flow from positive to negative
Charges
A physical property that causes matter to experience a force
- Protons are positively charged
- Electrons are negatively charged
Attract
Being drawn to another object
* Opposite charges attract
Repel
To push something away from something
* Same charges repel
Electricity
Energy resulting from charged particles
Static electricity
An imbalance of electric charges within a material
Electric field
The area around an electric charge that experiences an electric force
Electric current
When electric charges move
Open circuit
A path that electricity flows along that interrupted or disconnected
Closed circuit
A complete path of electrical connection which a current flow circulates
Series circuit
One path through which electricity flows
Parallel Circuit
Multiple paths for electricity to flow from one point to another
