General
When two magnets push away from one another; happens when two north or two south poles meet.
What is repelling?
When two magnets draw toward one another; happens when a north and south pole meet.
What is attraction?
A buildup of electric charge on an object or surface.
The amount of charge that travels past a fixed point in an electric circuit each second.
What is an electric current?
Current that flows from the positive side of the battery to the negative side. (This is the way current is drawn in circuit diagrams, even though it is wrong.)
What is the conventional current?
When a glass rod is rubbed with a neutral silk cloth, the glass becomes positively charged. What charge does the silk now have? Why?
What is negative, the glass rod lost electrons to the silk through fiction?
A place on a magnet where its pulling force is the strongest.
What is a magnetic pole?
What is a open circuit?
The cause of electromagnetic force.
What is the exchange of photons?
The ability of a material to impede the flow of charge.
What is resistance?
The atoms in an object are not aligned. Is the object a magnet?
What is no?
Is it possible to have a permanent magnet with only a north pole?
What is no?
Materials that allow electric current to flow through easily.
What are conductors?
What is a parallel circuit?
Charging an object without direct contact between the object and a charge.
What is charging by induction?
Two charged particles are placed 10 cm from each other and the resulting force is measured. The charge on object 1 is then doubled and the charge on object 2 is left the same. Also, the distance between the objects is reduces to 5 cm. How does the new force compare to the old force?
What is new force is 8 times stronger than the old one?
Is it possible to make a magnet from something that is not a magnet?
What is yes?
If a circuit has low voltage, is there a way to get alot of energy from it? If so, how?
What is yes, as long as you put a lot of current through it?
Materials that do not carry electric current easily.
What are insulators?
A small "package" of light energy that acts like a particle.
What is a photon?
The force between the south pole of one magnet and the south pole of another magnet is measured. If the distance between those magnets is suddenly doubled, how will the new force compare with the old one? Is the force attractive or repulsive?
What is the force decreases by 4 and is repulsive?
What is 2 north and 2 south poles?
Three lights are in a circuit. When one burns out, they all go out. What type of circuit is this?
What is a series circuit?
You are blindfolded and handed two extension cords of equal length. Both have the same current running through them. If the cord in your left hand is armer than the one in your right hand, which cord is thicker?
What is the cord in your right hand?
Charging an object by allowing it to come into contact with an object that already has an electrical charge.
What is charging by conduction?
