Amazing Atoms
Location of protons in the atom.
Nucleus
The north to which compasses always point.
Magnetic north
While trying to show that electricity and magnetism were not related, this Danish physicist ran an electric current near a compass and saw the needle change position.
Hans Christian Oersted
This American scientist and inventor wanted to determine if lightning and electricity were related.
Benjamin Franklin
This region of the electromagnetic spectrum passes through soft tissue and can help doctor's see inside their patients.
X-rays
The subatomic particle that moves in electricity.
Electron
A magnet that can be switched on and off is called this.
An electromagnet
This poor Brittish scientist made the most of the gifts God gave him and was able to demonstrate that a magnet moving through a coil of wire could generate electricity.
Michael Faraday
This is a closed path through which electric current can flow.
Circuit
Maglev trains operate based on this property of magnets.
Like charges repel
The charge of an atom that has an equal number of protons and electrons.
0
Even the tiniest magnets possess both of these.
A north and a south pole.
The work of this Scottish physicist brought together electricity, magnetism and light into four remarkable equations and helped verify what Faraday had observed in the lab.
James Clerk Maxwell
This is a stationary electric charge
Static electricity
This scientist determined that magnetism can be lost if metals are heated above a certain temperature.
Pierre Curie
The result of a positive charge and a negative charge approaching one another.
Attraction
Charged particles from the sun that penetrate the Earth's magnetic field produce this.
The Northern Lights
This German-born physicist and mathematician worked as a patent clerk when he published his first four papers. He often conducted thought experiments which helped him develop his Theory of Relativity.
Albert Einstein
He invented the first battery.
Alessandro Volta
The equation relating energy, mass, and the speed of light for which Einstein will always be remembered.
E=mc2
The overall charge of an atom with 7 electrons and 5 protons.
-2
Michael Faraday discovered that moving a magnet through a coil of wire produced this.
Electricity
This English physician sought the truth about magnetism and conducted experiments to determine its properties, then published his results.
William Gilbert
"What God hath wrought!" was the first official message sent between Washington DC and Baltimore by this artist who desired to develop a method of sending speedy messages.
Samuel Morse
The metric unit for frequncy is named for this scientist.
Hertz
