Equations & Laws of Magnetism
100
The scientist who first linked electricity and magnetism.
Who is Hans Christian Oersted?
100
A magnet that is allowed to freely rotate. (Hint may be required)
What is a compass?
100
The amount of something that flows through a given area.
What is flux?
100
A set of rules often used to find 1) the direction of a magnetic feild produced by a current carrying wire, or 2) the magnetic force applied on a moving charge.
What are the Right Hand Rules?
100
States that an induced emf, E, in a closed wire is equal to the time rate of change in the magnetic flux, O.
What is Faraday's Law?
200
These objects where thought to be the only magnetic objects before Oersted's discovery.
What are certaint types of metals?
200
They attract oppisites, repel same, move objects at a distance, and both come in two forms.
What are the similarities of charges and magnets?
200
This is equal to 1 Tesla/meters^2 and measures magnetic flux.
What is the SI unit weber?
200
A material in which the atoms aline in just the right manner, allowing for a magnetic feild that can noticable effect the material's surrondings.
What is a ferromagnetic material?
200
Faraday's Law in an equation form.
What is E = - ^O(b)/^t ?
300
The problem that has led to the confusion of the magnetic poles and geographic poles.
What is the assumption that a compass points to the "North pole"?
300
The main difference between magnets and charges.
What is the inseperatable poles?
300
This is effected by the strength of a magnetic feild, the area of a surface, and the angle from the surface.
What is Magnetic Flux?
300
This is the angle at which the magnetic flux is the greatest.
What is parallel or anti-parallel (when concerning magnetic flux)?
300
This explains why there is a negatice sign in Faraday's equation.
What is Lenz's Law?
400
The signifigant discoveries of this person led to the invention of the electrc motor we use today.
Who is Michael Faraday?
400
Is an important explaination of how a magnetic feild works.
What is a magnetic pole?
400
This will oppose the change in magnetic flux.
What is an induced current and magnetic feild?
400
When the feild lines are striking the surfce head-on, like an arrow hitting a target.
When is the magnetic flux equal to 0?
400
The value Maxwell calculated by using the permiability of free space constant and the emf constant.
What is the speed of light?
500
The book that James Maxwell published in which he connected electricity and magnetism, in four simple equations.
What is James Maxwell's A Dynamical Theory of Electromagnetic Feild?
500
You are using a compass to disern the direction you must go to arrive at a position 1 kilometer to your north. To which magnetic pole is your compass pointing?
What is the magnetic South Pole?
500
With this value you could find the amount of current flowing through a conducter that has an induced current.
What is the resistance?
500
This is law is given in the USAD packet but the experiment used to find this is unclear.
What is Lenz's Law?
500
This scientist said "... light itself... is an electromagnetic disturbance in the form of waves propigated through the electromagnetic feild."
Who is James Maxwell?
