Which is TRUE about an insulator?
It can be a good conductor.
It allows heat to pass through easily.
It slows energy transfer
It provides heat to keep materials warm.
slows energy
What is the difference between a bar magnet and a electromagnet?
Bar magnets maintain a constant magnetic pull, but electromagnets can be turned on or off.
this magnetic does not have a power source, strength cannot be adjusted, can attract other magnetic objects.
bar magnet
what happens in order to make a ballon stick to a wall.
electons have to be attracted to positive wall.
The handles of our cooking utensils at home are usually made of rubber or hard plastics that do not allow heat to pass through them. is this a conductor?
no
Insulators prevent _____ from traveling from atom to atom.
ELECTRONS
if a magnet doesn't need a power source, can't be turned on and off, and can't be made stronger what is it?
compass
this magnet needs a power source, strength can be adjusted, and can attract magnetic objects.
electromagnet
why is electrical wires made from copper.
negative particles move from cloth to ballon then ballon attracts to a positively charged wall.
