Two Magnets Walk into A Bar
Wait, Which Hand?
Allow me to Induce Myself.
Magnets, How do they work?
100
Permanent Magnets have two separate magnetic poles. They are called what?
The North Pole and the South Pole.
100
The technique/tool/secret handshake we can use to figure out the direction of a magnetic field cast by a wire.
The Right Hand Rule
100
Magnetic induction is the process of using a magnetic field to change kinetic energy into what other kind of energy?
Electrical Energy
100
This the unit for measuring magnetic field. (Two possible answers!)
Gauss
Tesla
200
The magnetic field around a bar magnet points away from which pole and towards which pole?
Away from North and towards South.
200
What is the direction of the magnetic field at the location marked "B"?
Into the board.
200
This machine uses magnetic induction to create electrical energy by using the energy of the wind, or some burnable chemical to turn a turbine.
A Generator
200
The Earth is a giant bar magnet. Where geographically is the Earth's Magnetic North Pole?
In Antarctica (The Geographic South Pole)
300
A bar magnet is formed when the magnetic ___________ within a material align with each other.
Magnetic Domains
300
The magnetic field is given in red. In what direction is the current flowing through the point marked "I"?
Out of the board
300
We move a magnet through a loop of wire to create a current with induction. If we increase the number of loops, what will happen to the voltage generated?
The Voltage will Increase
300
This is the name of the scientist who discovered that electrical currents create magnetic fields.
Oerstead
400
If I set two magnets with their North Poles facing each other, how do they respond?
The magnets will repel away from each other.
400
At a distance of 10 cm from a wire, we measure the magnetic field as being 10 G. What magnetic field would we measure at a distance of 5 cm?
20 G.
400
We move a magnet through a loop of wire to create a current with induction. If we use a stronger magnet, what should happen to the current?
The current will increase.
400
The equation which allows you to calculate the magnetic field cast by a current carrying wire. (Bonus points if you can tell me the equation!)
Ampere's Law
B=μ0I/2𝝅r
500
Only particular metals are magnetic, and others are not. Name either a metal which is magnetic, AND metal which is NON-magnetic. Be sure to indicate which is which!
Magnetic: Iron or it's derivitives, Neobdinium, Manganese, Cobalt, Nickel
Non-Magnetic: Copper, Aluminium, Gold, Silver, Brass
500
A wire carries a current to the right across the page. A second wire beneath it does the same. What is the TOTAL magnetic field between the wires?
0. The magnetic ieelds will cancel out.
500
We move a magnet through a loop of wire to create a current with induction. If we slow the magnet down, what should happen to the current?
The current will decrease.
500
This device uses magnetic induction to convert between a high voltage current in one wire and a low voltage current in a different wire.
A transformer.
