What is a repeating disturbance that transfers energy from one place to another ?
The highest point of a wave is often called this
What is the crest?
In magnet, much like a relationship, this rule of attraction is true.
Opposite (poles) attract.
A balloon is more likely to experience this type of electricity, as it stays relatively motionless
What is static electricity?
The lowest point of the wave is called this
What is the trough?
Circuits have to be this in order for electricity to flow all the way to a device/light source
What is closed?
This part of the Earth contributes to its large magnetic field
What is its core?
Electricity as an energy comes from this part of the atom.
What are electrons?
The constant rotation of electrons in an atom leads to this "attractive" force
What is magnetism?
These 4 materials conduct electricity
What are silver, gold, copper, steel, and/or sea water?
By this process, magnets can actually generate electric currents
What is induction?
A wave with a higher frequency is more likely to have a high amount of this.
What is energy?
When a wave bounces off of a certain surface, we are seeing this "mirror-like" wave property
What is reflection?
The distance between one wave crest to the next wave crest shows us this.
What is wavelength?
magnets as generators serve many uses, including these devices
Motors, credit cards, MRIs, and speakers/headphones
These types of waves are examples of low-frequency, harmless waves
What are radio waves, wi-fi, ocean waves?
If the wires serve as the conductor for electricity, then a rubber lining would serve as this.
What is an insulator?
These materials, though metallic, are NOT magnetic
What are aluminum, copper, brass, and lead?
Electromagnetic waves, unlike mechanical waves, have no need for this to travel
What is a medium?
These types of waves are often considered high frequency and harmful to humans.
What are X-rays, UV rays, nuclear radiation?
