Magnetism Test Study Guide
What was the cause and effect relationship between adding more magnets and the distance the paperclip jumped?
Every time we added an extra magnet (the cause), there were bigger and bigger increases in the jump distance of the paper clip (the effect). This is because each time we added a magnet, the force became stronger.
People often stick notes and other objects to refrigerator doors, using magnets. Understand what would happen if things do or don't stick to the refrigerator.
If something doesn't stick to a fridge, it's because the material is too thick, and the magnet isn't strong enough. The particles have to line up in the fridge, so if they don't, the material won't stick. It all depends on the size/strength of the magnet, the thickness of the material, and the particles
If I have a bar magnet and cut it into six pieces what will it look like and what can you tell me about what happened.
If you have a bar magnet and cut it into six pieces, you would then have 6 smaller magnets. Each piece would be their own individual magnet that has its own north and south pole. They would look and act the same as a "normal magnet."
Potential energy
Non-moving energy (stored energy)
On the pulling cups apart investigation what were we testing for?
On the pulling cups investigation we were testing how much distance we could put between two magnets, but still have them attract. We also wanted to see if the force of attraction between the magnets would get weaker or stronger as we added more distance between them. All of this was happening in the magnetic field, so that is basically what we were testing.
A student has a magnet and a paper clip. Trial 1: She holds the magnet 3 cm away from the paper clip and watches the paper clip jump to the magnet. Trial 2: She holds the magnet 9 cm away from the paper clip but the paper clip does not move. Draw two diagrams to show what happened in each trial. Be sure to represent the magnetic field in some way in each of your diagrams.
Practice and understand the drawings. Be sure to label everything.
Kinetic energy
The energy of an object when it is moving from the state of rest to motion (energy in motion)
On the jumping paper clip investigation, what were we testing for?
We were testing how strong the magnetic field was. As we added more magnets, the magnetic field got stronger. We wanted to see how strong the force of the magnet's magnetic fields could get.
Induced magnetism
You are introducing magnetism to another thing (which is usually made of iron/steel because that's the only thing that works)
Permanent magnet and examples:
a permanent magnet is a magnet that is always magnetic; it never loses its magnetism (the opposite of a temporary magnet), some examples of permanent magnets: the North and South Pole of Earth, horseshoe magnets, refrigerator magnets, and braces are some examples of permanent magnets
Magnetic field
An area of magnetic influence around a magnet
What was the cause and effect relationship between adding more spacers and the newtons?
As we added more distance between the magnets with the spacers (the cause), the weaker the force became (effect). And that's why the average in Newtons kept going down each time we added an extra spacer.
Temporary magnet and examples:
A temporary magnet has magnetism that doesn't last forever (the opposite of a permanent magnet), some examples: paper clips, iron nails, and other iron/steel objects (they attract to iron and steel objects)
