magnetism and energy Flashcards
motion or interaction of molecules, the ability to do work
energy
subatomic particle that has a negative charge
electron
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
magnetism
a region around a magnetic material where the force of magnetism acts
flow from positive to negative
magnetic field
a physical property that causes matter to experience a force
protons= positively charged
electrons= negatively charged
charges
being drawn to another object
opposites attract
attraction
to push away from something
same charges repel
repel
energy resulting from charged particles
electricity
an imbalance of electric charges within a material
static electricity
the area around an electric charge that experiences an electric force
flow from positive to negative
electric field
when electric charges move
electric current
a path that electricity flows along that is interrupted or disconnected
open circuit
a complete path of electrical connection around which a current flows or circulates
closed circuit
one path through which electricity flows
series circuit
multiple paths for electricity to flow from one point to another
parallel circuit
