magnets
what do magnets do ? do they only repel or only attract or do they do both
both
how do we use turbine generators?
we use them for electricity
magnet core can help speakers make sound but how does a speaker work? 1.it vibrates to make sound 2. it shakes on the floor 3. it uses water
it vibrates
the jump of electrons from one place to another to balance charge is also called an
electrical discharge
magnets can be used to ___ heavy stuff in junk yards
lift
what do we use magnets for that is a part of a turbine generator
we use it for the rotor
what do the magnets in the rotor do?
they spin to make the mechanical energy into electricity

what are magnet domains?
they are zones of a magnet that are naturally aligned
the turbine is turned by

magnets
Conductors allow energy to flow ___
easily
they are used in speakers but what do they do?
they bounce back and forth with the vibrations to make the sound

Completing this process stirs up electrical current in the wires and transforms the ______
mechanical energy into electrical energy
generators produce electricity they do this by...
alternating a current among copper wire using rotating magnetic fields
parralel circuits are hard to make and expensive but are they good? why
yes their good because adding more paths wont affect the electricity flow
a group of atoms that are able to be aligned or spin or move in the same direction are and If they are not aligned they are
magnetized if their not in the same direction or aligned they are unmagnetized
