Magnetism Flashcards
Magnetism
Attractive and repelling forces contained in magnetic materials
Magnetic Moment
Magnetic field generated by an electron
Magnetic North Pole
Area of Earth that magnetic materials align with
Law of Magnetic Poles
Opposite poles attracts similar poles repel
N = S
S = N
N X N
S X S
Ferromagnetic
Material with a strong attraction to magnetic fields
Iron and Colbalt are examples of Ferromagnetic materials
Ferro - Iron
Paramagnetic
Material that has a slight effect on magnetic fields
Aluminum gives a weak magnetic attraction
Diamagnetic or Nonmagnetic
Material that is unaffected by magnetic fields
Salt and Mercury are examples of nonmagnetic materials
Van Allen Belts
Donut-shaped magnetic fields surrounding the earth
Aurora Borealis
Northern Lights
Aurora Australis
Southern Lights
Aurora Oval
The latitudes surrounding the poles in which Auroras occur
The area in which the Auroras can occur in the north or south pole
Solar Maximum
When sunspot activity is highest
Solar Minimum
When sunspot activity is lowest
Magnetosphere
The Earth’s magnetic field
What does Van Allen’s belt do?
It traps harmful radiation in the form of charged particles from the sun and protects the earth from them
Geographic North Pole vs. Magnetic North Pole
The geographic north pole is located at the northmost side of our plantet.
The magnetic north pole is where the highest consentration of magnetic force is located on the earth.
Magnetic North Pole: Resolute Bay, Canada in the Arctic Ocean
Fun Fact #1!
The earth’s magnetic field decreases a little each year. If this decreasing has been constant in the past, this would prove the earth much younger than evolutionist believe it to be.
APOLOGETICS!
Relating to Fun Fact #1
Fun Fact #2!
The earth would seem to lose half of it’s energy every 1,460 years. If the rate of decay is constant, the magnetic field would have been so strong only 20,000 years ago that it would have caused massice heating in the Earth’s crust and would have killed all life on Earth. This supports the idea of an Earth that is only about 6,000 years old, as indicated in the Bible
Which means if the earth is 6000 years old and we lose half of our energy let’s just say every 1500 years, then we’re at 1/16th of our original power
Electromagnet
Magnetic field generated by current flowing through a wire
Generator
Mechanism for converting a changing magnetic field into a flow of current
Like converting a magnetic field into energy
Motor
Mechanism for converting changing current inside a magnetic field into mechanical energy
