What is the relationship between heat and electricity? Provide metaphor.
Heat is created when electricity loses energy through friction. A clap sound is created by the contact of your hands together the heat is created by friction.
Why is it warm near an incandescent bulb?
The mercury atoms in the bulbs are bouncing around so much that heat is created by friction.
What is a superconductor? Uses? How could one make a metal superconductor?
A superconductor is a substance capable of becoming superconducting at sufficiently low temperatures. One use of superconductor is in MRI machines.
Ampere's Law?
The magnetic field in space around an electric current is proportional to the electric current which serves as its source, just as the electric field in space is proportional to the charge which serves as its source.
If current of the same size flows in the same direction in two electric wires placed side by side, the magnetic fields repulse each other and they would attract each other if the flows were in opposite directions.
