Force Fields
These are the kinds of invisible force fields
What are electric and magnetic force fields?
These are the two types of electric charge
What are positive and negative?
The magnitude of a current will increase if this is done to the voltage in a circuit.
What is increase?
This is what happens to the strength of a magnet when the distance between magnets is increased
What is it decreases?
This is what a solenoid is
What is a coil of wire
This is what happens to the strength of a force field when the objects get closer together
What is it increases/gets stronger
This is what will happen when a positively charged object comes close to a negatively charged object.
What is they will attract?
The magnitude of a current will decrease if this is done to the length of a wire in a circuit
What is increase?
These are the factors that affect the strength of a magnetic force
What are size of magnet, distance of magnet, and material of magnet?
Increasing the number of coils in a solenoid will affect the strength of an electromagnet in this way:
What is it will increase?
These are the opposite sides of a magnetic force field
What are the north and south poles?
Electrons have this type of charge
What is negative charge?
This is anything that slows the flow of electricity in a circuit
What is resistance?
This is why we call the opposite sides of magnets the north and south poles
What is because they align to the north and south poles of Earth?
These are the three factors that affect the strength of electromagnets:
What are number of coils in the solenoid, strength of current, and size of iron core
This is what happens when objects with the same magnetic pole or same electric charge come close together.
What is they repel?
This is what happens to the number of electrons when an object becomes positively charged.
What is the object loses electrons?
These are the factors that affect the amount of resistance in a circuit
What is the length of wire, thickness of wire, and material of a wire
This is how you can increase the potential energy of two REPELLING magnets
What is push them closer together?
You can induce an electric current in a wire by moving a magnet through a coil. This is how you can INCREASE the strength of the current:
What is move the magnet faster through the coil?
This is why a magnet on one side of a room will not attract a magnet on the other side of a room.
What is they are too far away?
This is the title of Charli XCX's most recent album
What is brat?
This is the independent variable in the following testable question: "How does the material of a wire affect the magnitude of a current?"
What is the material of the wire?
This is why rubbing a nail with a magnet will turn the nail into a temporary magnet (use the word domains in your answer)
What is the magnetic domains in the nail become aligned?
