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.
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 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. *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.
