Magnetism and Electricity
100
When two magnets push away from one another; happens when two north or two south poles meet.
What is repelling?
100
When two magnets draw toward one another; happens when a north and south pole meet.
What is attraction?
100
A buildup of electric charge on an object or surface.
What is static electricity?
100
The loop (path) along which an electric current travels.
What is an electric circuit?
100
Electricity always follows...
What is the path of least resistance?
200
When the magnetic field lines are close together that means the magnet is 
What is "strong"?
200
A place on a magnet where its pulling force is the strongest.
What is a magnetic pole?
200
Prevents the flow of electrons.
What is a open circuit?
200
When the lights are on, the electric circuit is....
What is an closed circuit?
200
A machine that uses a magnet to change mechanical energy into electrical energy.
What is a generator?
300
A magnet can generate electricity in a wire if it is close to the wire and it is.....
What is "moving"?
300
Magnets that hold their force for a short time after being taken away from a magnetic field.
What are temporary magnets?
300
Materials that allow electric current to flow through easily.
What are conductors?
300
This type of circuit that allows for all other loads to continue operating when one load burns out. All houses and businesses are wired this way.
What is a parallel circuit?
300
A wheel shaped like a fan that spins when acted on by a force.
What is a turbine?
400
Two metals that are attracted to magnets.
What are iron and nickel?
400
Materials in which the miniature magnets or domains are always aligned.
What are permanent magnets?
400
A magnet is set next to a compass. How would the needle of the compass react if the N end of the magnet is pointing toward it?
400
Materials that do not carry electric current easily.
What are insulators?
400
A student wants to set up an experiment to test different brands of battery in order to determine which brand consistently generates energy for the longest period of time.
Name the independent variable, the dependent variable and at least two constant variables.
IV: brand of battery
DV: how long the battery generates energy
constants: the object that the batteries are powering, how old the batteries are, the battery voltage, all objects are switched on at exactly the same time
500
Electric current in a wire causes....
What is an "magnetic field"?
500
What will increase the strength of an electromagnet?
Increase: number of coils of wire
or number of batteries attached
500
When a permanent magnet moves through a coil of wire connected to a light bulb, the light bulb glows. How can the magnet make the light bulb glow?
The motion changes the magnetic field which causes electrons to move in the wire.
500
Would adding batteries to a circuit attached to a small motor affect the speed of the motor?
What is "Yes" because increased electrical force increases magnetic force in the motor
500
Washing machines and blenders and other common appliances rely on a common technology. Which of the following best describes the energy conversion taking place?
A. Mechanical energy is converted to electrical energy using magnetic fields.
B. Electrical energy is converted to mechanical energy using magnetic fields.
C. Magnetic energy is converted to mechanical energy using electrical energy.
D. Electrical energy is converted to magnetic energy using mechanical energy.
B. electrical energy is converted to mechanical energy using magnetic fields
