---|---|---|---|---|
What is a conductor
This allows electricity to flow easily through.
|
What is North and South pole
All magnets have these, even if they are cut in half.
|
What is increase its strength
Increasing the number of coils in an electromagnet will also do this
|
What is attractive / static electricity
If you rubbed a balloon on your sweater and then held the balloon above salt. Which force would you witness?
|
What is magnetic field
a line of force running from the north-seeking pole to south-seeking pole of the magnet
|
What is induction
A method used to charge an object without actually touching the object to any other charged object.
|
What is permanent magnet
Made of material where the magnetic field is generated by the internal structure of the material itself
|
What is NONE - trick question
A neutron exerts this type of field
|
What is neutral
If you just blew up a balloon, the charges would be this
|
What is electric field
this field can exist when a charge is stationary
|
What is electric current
A stream of charged particles, such as electrons
or ions, moving through an electrical conductor or space. |
What is pointing in all different directions
The domains of unmagnetized items take on this formation
|
What is the right-hand-rule
We can use this rule to determine the direction of the magnetic field, if given the current
|
What is magnetic
MRIs utilize this type of field
|
What is magnetic field
form continuous loops
|
What is parallel
In these electrical circuits, the flow of electrons can take multiple paths
|
What is molten iron and nickel in its core
Earth's magnetic field comes from this
|
What is increasing current
This increases the strength of the magnetic field around a current
|
What is electromagnet
Junk yards and recycling centers may use these to move large amounts of metal material
|
What is both fields exist
If a charge is moving...
|
What is kinetic electrical energy
This is a type of electrical energy - when the electrical charge is moving.
|
What is attractive and repulsive
The two magnetic forces
|
What is iron, nickel, or cobalt
In order for an electromagnet to be formed, an electric current must pass through a coil of copper wire wrapped around an ________ core.
|
What is series
Holiday lights are a good example of this type of electrical circuit.
|
What is the poles
magnetic fields are strongest here
