Magnetism and electricity Flashcards
Energy
motion or interaction of molecules ,the ability to do work
Electron
Subatomic particle that has a negative charge
Magnetism
A force that can attract or repel objects that contain a magnetic material inside them
-caused by electrical charges
-magnetic materials:cobalt,nickel,iron,magnetite
Magnetic field
A region around a magnetic material where the force of magnetism acts
*flow from positive to negative
Charge
A physical property that cause matter to experience a force
-Protons are positively charged
-Electrons are negatively charged
Attraction
Being drawn to another object
*Opposite charges attract
Repulsion
To push 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 the experiences an electric force
*flow from positive to negative
Electric current
when electric charges move
Open circuit
A path that electricity flows along that is interrupted or disconnected
Closed circuit
A complete path of electrical connection around which a current flows or circulates
Series circuit
One path through which electricity flows
Parallel Circuit
Multiple paths for electricity to flow from one point to another
