Magnetic Field
The mnemonic device to remember the direction of a magnetic field.
Right-Hand Rule
The constant streaming of individual protons and electrons from the Sun's surface.
Solar Wind
The unit of measurement for electric current.
Amps
Wires arranged to form multiple circular loops on top of each other
Solenoid
Current that is switching directions.
Alternating Current
(AC)
What is the fundamental unit of magnetism?
magnetic dipole
A type of gas so hot that atomic nuclei cannot hold onto any electrons.
Plasma
The unit of measurement to measure the strength of a magnetic field
Teslas
A device that converts electrical energy into mechanical motion
Motor
A device that creates a high voltage on a metal ball on top of a coil of wire, strong enough to create lightning bolts.
Tesla Coil
Materials that temporarily become magnetic as long as they're in another object's magnetic field
Paramagnetic
___ is an observation-based science
Physics
The tool used to determine the atomic composition of an unknown sample
Mass Spectrometer
A device that converts mechanical motion into electrical energy
Generator
A device that only allows current to flow in one direction
Diode
Materials that when exposed to a strong magnetic field for a long time, permanently become magnetic
Ferromagnetic
When the Sun's magnetic pole switches, and parts of the Sun's surface get ejected.
Coronal Mass Ejections
(CMEs)
The effect where the magnetic force causes particles to move in a circle.
It does not change the speed of the object, but does change the direction.
Centripedal Force
Who discovered that a changing magnetic field can generate current in 1831?
Michael Faraday
A solenoid attached to a circuit that resists changes in current to the electric circuit
Inductor
The Greek coastal district where iron-attracting lodestones were found.
Magnesia
___ first observed that a wire with an electric current creates a magnetic field in 1820.
Hans Christian Oersted
Fb = q v B
The equation for the Magnetic Force
The law specifically for the negative sign for Faraday's law
Lenz's Law
Who created the arc lamp?
Humphrey Davy
