CURRENT Events
What is an electric current?
The flow of electricity from place to place.
What is a magnet?
A material that produces a magnetic field.
Why is it static electricity not very useful?
It is released all at once.
What is a conductor?
A material that allows electrons to move through it easily.
What are dry cell batteries?
Batteries that have a paste or gel inside them instead of a liquid.
Where would we find a 'hot slot'?

What is an electromagnet?
A magnet created by an electric current through a wire and can be turned on and off.
When electrons flow back to the cathode, what process do they undergo?
Reduction.
