Energy and Circuits
This is the part of the lightbulb that produces light.
What is the filiment?
This is the force, or the push and pull, between magnets.
What is the Force of Magnetism?
In an electromagnet, this is the material around which a coil of insulated wire is wound. (Another word for 'the center of something')
What is a core?
This is the lowest point of a wave form.
What is a trough?
True of False: Humans can see more colors and light waves than any other known animal on Earth.
What is false?
This does not allow electric current to flow.
What is an insulator?
If two magnets come together at two like poles, what will they do?
What is repel?
A property of electric and magnetic fields that causes interactions with electric charges and currents.
What is electromagnetism?
This is the speed at which something oscillates.
What is frequency?
What is steel?
This is the type of circuit when all components are all in a line, and they "share" the electricity.
What is a series circuit?
These are the two sides of a magnet.
What are poles?
This is a series of loops.
What is a coil?
This is a repeating pattern of motion (up and down or back and forth).
What is a wave?
True or False: sound moves faster than light.
What is false?
This is the component that opens and closes circuits.
What is a switch?
This is metal that sticks to magnets.
What is iron?
A piece of iron that becomes a temporary magnet when electricity flows through an insulated wire wrapped around it.
What is an electromagnet?
This is the highest point on a wave form.
What is the peak?
This is the distance from the center of one peak to the center of the next peak on a wave form.
What is wavelength?
This is an organized group of related objects that work together.
What is a system?
This is an instrument that is used to detect Earth's poles.
What is a compass?
An electromagnet does this the more a coil is wrapped around a core.
(Hint: Does the electromagnet become stronger or weaker?)
What is it becomes stronger.
This is the height of the peaks in a wave form.
(Hint: If the waves being observed are sound waves, this is volume.)
What is amplitude?
This is the type of energy matter has because of its motion.
