Magnetism part two
A display of lights in the sky, near Earth's poles,Colored light produced by charged particles from the solar wind and from the magnetosphere that react with and excite the oxygen and nitrogen of Earth's upper atmosphere; usually seen in the sky near Earth's magnetic poles
|A compass needle points north|| |
What effect does Earth's magnetic field cause?
|Like poles will repel each other; they will push away.||What happens when the same poles of 2 magnets are moved closer?|
|What causes a compass' needle to point north?||Earths Magnetic field|
|How do you tell which part of a bar magnet is south?||Use a compass; north points to the south part of the magnet.|
|Repel (Repulsion)|| |
Force that pushes like poles apart. Like poles repel (N+N) (S+S) To push or move away
|Magnetic field|| |
The force around all magnets
|Magnetic poles|| |
The ends of the magnet, where the magnetic force is the strongest
Groups of atoms that line up to makes something magnetic
|Attract (Attraction)|| |
Force that pulls unlike poles together Opposite poles attract (N+S).
|Lines of Force||Imaginary lines used to illustrate and describe the pattern of the magnetic field. The magnetic lines of force are assumed to emanate from the north pole of a magnet, pass through surrounding space, and enter the south pole. The lines of force then travel inside the magnet from the south pole to the north pole, thus completing a closed loop .Magnetic lines of force will never cross one another.|
|Where are magnets the strongest?||The poles|
A navigational instrument that finds directions using Earth's magnetic field
A magnetic field surrounding the Earth (or a palnet), which deflects much of the solar wind so that only a small portion of it enters the atmosphere
|Solar wind|| |
Streams of electrically charged particles flowing at high speeds from the sun; solar wind pushes against Earth's magnetic field and surrounds it.
|Cutting a magnet||.An interesting characteristic of magnets is that when you cut a magnet into parts, each part will have both N and S poles|
