The proportionality relationship between distance and the strength of the magnetic force exerted by a magnet.
Inverse
The Magnetic North Pole is located where?
The Geographic South Pole.
Paper clip, nail, and iron filings are all examples of this kind of material.
Ferromagnetic.
The interaction of the nails as the two magnets are brought closer together.
The nails would move further outward away from each other.
3 Most common metals that are Ferromagnetic
Iron, Cobalt, Nickel.
What you see when you bring an unrubbed nail to a compass needle.
Attraction
At the poles.
Gold, Plastic, and Aluminum all have this in common.
Non-Ferromagnetic
The direction of the arrows on magnetic field Lines.
Outwards/away at the North Poles
Inwards/towards the South Poles

migrate
Two examples of force at a distance besides magnetism.
Gravity
Static Electricty
What we see when solar winds crash with Earth's Magnetic Field.
Aurora Borealis/Northern Lights
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.
Drawing challenge: A fully magnetized nail.
Teacher will judge. (Domains in nail should all face the same direction.)
3 Things you can do to increase the power of an electromagnet.
Increase the rod thickness.
Use a better conductor for the rod.
Wrap more coils around the rod.
Increase the battery Voltage
Have more batteries.
The two magnets that will experience the greatest force between them.
Magnets 1 and 2.
The length of time it takes for Earth's magnetic poles to shift and change location?
Hundreds of thousands of years (example: 300,000)
The two different types of magnetic objects
Temporary & permanent
Drawing challenge: A somewhat magnetized nail.
Teacher will judge. (Domains mostly aligned with some exceptions.)
