Repel
When you put two south poles together, what happens?
They repel each other.
When you put opposite poles together, what happens?
They attract each other.
If you label one side of a magnet with an "N", what does that mean?
If you label one side of a magnet with an "S", what does this mean?
It is the south pole end
What is Kinetic energy?
Magnets are unable to stick to plastic. Why is this?
Because plastic does not contain molecules that are magnetic
Name two types of metals that attract magnets.
What is force?
A push or a pull, an interaction between two objects
If you cut a permanent magnet into four pieces, what will you have?
a. 4 temporary magnets
b. 2 temporary and 2 permanant magnets
c. 4 permanant magnets
What is Potential energy?
Energy stored based on the object's position
If you place the south pole side of a magnet against a compass, what direction does the compass show?
South
What happens to the force of attraction when you increase the distance from the magnet?
The force of attraction weakens
If an iron nail is stuck to a magnet and you hang more nails from the original nail, what does the iron nail become?
a temporary magnet
What does it mean to induce magnetism?
When you put iron or nickel against a magnet and it attracts other magnetic objects, making it into a temperorary magnet
What invisible force extends out from the poles creating a field?
Magnetism
Every magnet has 2 of these. What are they?
Poles
What does gravitational force do?
It attracts.
A paperclip was placed at 0mm and once the magnet was moved close enough, the paperclip moved. Why did this happen?
Because the magnetic field became strong enough to attract the paperclip.
What force might keep a paperclip from moving closer to the magnet?
Friction
How would you define a compass?
An instrument used to show direction and uses the Earth's magnet to guide the arrow towards the North pole.
What are three invisible forces?
Gravity, magnetism, and electricity
Name three objects you could use to detect the location of a magnet.
compass, another magnet, and a metal that is magnetic
What is the relationship between the force of attraction and distance?
The greater the distance, the weaker the attraction. The smaller the distance, the stronger the attraction.
Explain how the Earth is a giant magnet.
The Earth has two poles and the force of gravity attracts objects like a magnet. It also has a magnetic core which causes compasses to point north.
What are objects that are magnetic all the time?
Permanent magnets
