Magnetism I
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 loop (path) along which an electric current travels.
What is an electric circuit?
An invisible area where magnetic forces are present.
What is a magnetic field?
A place on a magnet where its pulling force is the strongest.
What is a magnetic pole?
An electric circuit with no breaks.
What is a closed circuit?
An electric circuit with a break in it.
What is an open circuit?
This is a giant example of a magnet
What is the earth?
Which two poles will repel from one another
N-N or S-S
Materials that allow electric current to flow through easily.
What are conductors?
A diagram that uses symbols to show all of the parts and path of a circuit
what is a schematic diagram?
Two metals that are attracted to magnets.
What are iron, cobalt, and nickel ?
type of magnet in which the magnetic field is produced by an electric current
What is an electromagnet?
an electrical component that can disconnect or connect the conducting path in an electrical circuit
What is a switch?
Materials that do not carry electric current easily.
What are insulators?
The result of particles from the Sun interacting with Earth's magnetic field.
What are the Northern Lights (Aurora Borealis)?
What are lines of force?
The two locations on a battery that must have a path to one another to create an electric circuit.
What are the positive and negative terminals?
a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space
What is an electric current?
