100
It's a material through which electrons can easily move.
What is an electric conductor?
100
It's an unbalanced negative or positive electric charge on an object.
What is a static charge?
100
It's the amount of energy the source uses to move one coulomb of electrons through the circuit.
What is voltage?
100
It's a region in a magnetic material in which the magnetic fields of the atoms all point in the same direction.
What is a magnetic domain?
100
It's a core of ferromagnetic material magnetized by an electric current flowing in a wire coil that surrounds it.
What is an electromagnet?
200
It's the process of an unbalanced electric charge becoming balanced.
What is an electric discharge?
200
It's a closed, or complete, path in which an electric current travels.
What is an electric circuit?
200
It's an electric circuit with more than one path, or branch, for an electric current to follow.
What is a parallel circuit?
200
It's a place on a magnet where the force it applies is the strongest.
What is a magnetic pole?
200
It's a type of electric current that changes direction in a regular pattern.
What is alternating current?
300
It means providing a path for electric charges to flow safely into the ground.
What is grounding?
300
It's the movement of electrically charged particles.
What is electric current?
300
It's an electric circuit with only one path for an electric current to follow.
What is a series circuit?
300
It's a magnet that remains a magnet after being removed from another magnetic field.
What is a permanent magnet?
300
It's type of electric current that flows in one direction.
What is direct current?
400
It's a material through which electrons cannot easily move.
What is an electric insulator?
400
It's a measure of how difficult it is for an electric current to flow in a material.
What is electric resistance?
400
It's an element that has an especially strong attraction to magnets, such as iron, nickel, and cobalt.
What is a ferromagnetic element?
400
It's a magnet that quickly loses its magnetic field after being removed from a magnetic field.
What is a temporary magnet?
400
It's a device that uses a magnetic field to transform mechanical energy to electric energy.
What is an electric generator?
500
It's when electrons concentrate at one end of an object.
What is polarized?
500
It's a mathematical equation that describes the relationship between voltage, current, and resistance.
What is Ohm's law?
500
It's any object that attracts the metal iron.
What is a magnet?
500
A device that uses an electric current to produce motion.
What is an electric motor?
500
It's a device that changes the voltage of an alternating current.
What is a transformer?
