Opposites Attract
An object that attracts certain metals.
What is a magnet?
A form of energy that involves the flow of electrical charges.
What is electricity?
An object that does not allow electricity to flow through it.
What is an insulator?
Electric current in a wire makes the wire act like a:
What is a magnet?
Produces electricity by using a coil of wire and a magnet.
What is a generator?
The pushing or pulling force caused by a magnet.
What is magnetism?
Occurs when electrical charges build up on the surface of an object.
What is static electricity?
An object that allows electricity to flow through it.
What is a conductor?
A temporary magnet that forms when electric current flows through a wire coiled around certain materials.
What is an electromagnet?
Moving a magnet through a coil of wire creates:
What is an electric current?
Ends of a magnet where a magnet's magnetism is the greatest.
What are poles?
All matter is made up of small particles that have:
What is an electrical charge?
A continuous flow of negative charges through a material.
What is current electricity?
What items can be used to create an electromagnet.
What is a power source (battery), wire, metal such as a nail?
Water, steam or wind is used to turn the turbines to make these work.
What are generators?
The area around a magnet where the force of the magnet can act.
What is a magnetic field?
An object that has the same number of positive and negative charges is called:
What is neutral?
A circuit that connects several objects in one complete path.
What is a series circuit?
True or False: the more you wrap the wire around the metal (nail) the stronger the magnetism.
What is true?
Two ways magnets are used to produce electricity.
What are generators and electromagnets?
True or false: magnets will attract on the same side such as a south pole and a south pole.
What is false: opposites attract! The north and south poles will attract. North/north and south/south will repel (push away from) each other.
True or false: negative charges move from object to object.
What is true? Positive charges do not move.
A circuit that has more than one path.
What is a parallel circuit?
When the current in an electromagnet stops it causes the magnetic force to:
What is stop?
True or False: magnetism and electricity are related.
What is true?
