Force at a distance
Earth's Magnetic Field
Magnetic or Not
Diagrams and Domains
100
The proportionality relationship between distance and the strength of the magnetic force exerted by a magnet.
Inverse
100
The Magnetic North Pole is located where?
The Geographic South Pole.
100
Paper clip, nail, and iron filings are all examples of this kind of material.
Ferromagnetic.
100
The interaction of the nails as the two magnets are brought closer together.
The nails would move further outward away from each other.
200
What you see when you bring an unrubbed nail to a compass needle.
Attraction
200
The Earth's magnetic field is strongest here.
At the poles.
200
Gold, Plastic, and Aluminum all have this in common.
Non-Ferromagnetic
200
The direction of the arrows on magnetic field Lines.
Outwards/away at the North Poles
Inwards/towards the South Poles
300
How will these two magnets interact?
Repel
300
Earth's Magnetic Field protects us from this.
Solar winds/flares
300
A magnet I can turn on and off.
An electromagnet
300
What happens to the domains in a magnetized paperclip when it is superheated.
They become randomized/unaligned.
400
Two examples of force at a distance besides magnetism.
Gravity
Static Electricty
400
What we see when solar winds crash with Earth's Magnetic Field.
Aurora Borealis/Northern Lights
400
How can a paper clip pick up another paperclip without linking the two together?
Magnetize of the paper clips by rubbing it with another magnet.
400
Drawing challenge: A fully magnetized nail.
Teacher will judge. (Domains in nail should all face the same direction.)
500
The two magnets that will experience the greatest force between them.
Magnets 1 and 2.
500
The length of time it takes for Earth's magnetic poles to shift and change location?
Hundreds of thousands of years (example: 300,000)
500
The two different types of magnetic objects
Temporary & permanent
500
Drawing challenge: A somewhat magnetized nail.
Teacher will judge. (Domains mostly aligned with some exceptions.)
