Like a small airport, a battery has two terminals. They are called _________ and __________.
What are positive and negative.
This man born in 1777, discovered the relationship between electricity and magnetism which led to electromagnetic force.
Who is Hans Christian Orsted.
This is the object needed to move electricity through a circuit.
What is a motor.
If caught outside during a lightening storm, the best place to be is in your car since electricity travels at this speed and could find you.
What is the speed of light. (300 million meters per second.)
His nickname was "The Wizard of Menlo Park".
Who is Edison.
What are electrolytes.
In an electromagnet, these objects carry the electricity from component to component.
What are wires.
In 1820, this man discovered that when he closed a circuit, the needle of a compass he had on the table rotated!
Who is Orsted.
In the experiment "Virtual Electromagnet" the wire gauge that was the _______________ created the strongest electromagnet.
What is thickest.
He had a vision to alternate current instead of having it go all in one direction.
Who is Nikola Tesla.
In an electromagnet, the battery has the potential to run the _________.
What is circuit.
In an electromagnet, the _________ controls the flow of electricity by opening and closing the circuit.
What is the switch.
For my friend's birthday party we wanted to hang up balloons. We ran out of tape and string so we used our hair to charge up the balloons. When we put the balloons near one another, they ____________ each other.
What is repelled.
In the experiment "Virtual Electromagnet" the wire made out of this metal created the strongest electromagnet.
What is copper.
Who's power system could only deliver power within a mile of the power plant.
Who is Edison
I conducted an experiment with batteries and wires. I added more batteries and more wires. I changed two variables. Too bad, this made my experiment __________.
What is invalid.
Strong electromagnets are used in these places to sort and organize different types of metals.
What are recycling centers.
What are the bulb casing and the base.
In the experiment "Virtual Electromagnet" when more _______ were added to the iron core, the electromagnet became stronger.
What are coils.
Which man's system was more dangerous?
Who is Tesla.
A battery is an energy source. Since energy cannot be created or destroyed, a battery changes energy from this type to this type.
In an experiment, can I increase the coils and decrease the amount of voltage in my electromagnet at the same time?
Explain your answer.
What is NO because you can not change two variables at the same time.
This section of the electromagnet becomes a temporary magnet allowing the flow of electricity.
What is the rivet, or core.
This is the material in a wire that keeps me from getting shocked.
What is the plastic insulation.
True or False:
Nikola Tesla is related to Elon Musk, the maker of the Tesla.
What is False.
