Why is it warm near an incandescent light bulb?What is a superconductor? What are they used for in real life? You may have to look this up. How could one make a metal a superconductor?What is Ampere's Law?If current of the same size flows in the same direction in two electric wires placed side by side, what happens?What happens if current of the same size flows in opposite directions in two electric wires placed side by side?Please read about Flemings Left and Right Hand Rule. Think about this Rule with respect to the motors we have made this week.
Heat is the light of my life. They are like two peas in a
pod.
The light made by the incandescent lightbulb produces heat.
The large amount of heat makes the light.
A super conductor is a super cooled metal that has no
electrical resistance, allowing a current to flow once applied without a
continuous power source. They are used in MRI machines and particle accelerators.
To make a super conductor, one needs liquid nitrogen.
Ampere's Law says that the magnetic field created by an
electric current is proportional to the size of that electric current.
If a current of the same size flows in the same direction and
if the two electric wires are placed side by side then a force of attraction is
produced by the two wires.
If opposite directions, then they cancel out.
