Bar Magnets have poles at the ends. One pole is the North Pole and the opposite is called the South Pole.
What Poles are on the Bar Magnet and Where?
Horseshoe Magnets have poles at the ends. One pole is the North Pole and the opposite is called the South Pole.
What are the Poles of the Horsehoe Magnet called and where are they?
What makes up a magnetic system?
Parts that interact with each other
What are the parts that make up the magnetic system?
the magnet
the object is attracts
the magnetic fields surrounding the magnet
What do magnets attract?
Materials containing:
iron
steel
nickel
cobalt
What is a magnet?
a piece of metal that can pull certain other metallic objects toward itself and hold them
Magnets can be used to separate these metals from other materials
example:
magnets are used in recycling to sort steel cans from aluminum, and steel parts from glass and plastic
What kinds of things can magnets attract?
things made out of:
iron
steel
nickel
Can a magnet attract objects without touching them?
YES
If the material between the magnet and the object is thicker is the magnetic force weaker or stronger?
WEAKER
Can magnets have different shapes?
YES
Can magnets have different sizes?
YES
Can magnets have different strengths?
YES
Where are magnets the strongest?
at their poles
Do two like poles repel or attract each other?
repel
Do two unlike poles repel or attract each other?
attract
Do the poles of two magnets always act in the same way when they are brought near each other?
YES
What makes up a magnetic system?
Parts that internact with each other
What are the parts that make up the magnetic system?
the magnet
the object is attracts
the magnetic fields surrounding the magnet
What do magnets attract?
Materials containing:
iron
steel
nicket
cobalt

Horseshoe Magnets have poles at the ends. One pole is the North Pole and the opposite is called the South Pole.
What are the Poles of the Horsehoe Magnet called and where are they?
What is a ring magnet?
one flat surface is the North Pole and the opposite is the South Pole.
If you place a magnet close to a computer will it erase everything on the computer program?
YES
What does repel mean
Push away from
what does attract mean?
pull towards something
What is a magentic field?
the space around which the force of a magnet is felt. Evidence of a magnetic field can be observed by using iron filings
Does the shape of the magnetic field vary with the shape of the magnet?
Yes
pattern of magnetic fields
1. distance between the line of force are greatest where the force is the weakest.
Pattern of magnetic field
2. lines of force are closest together at the poles where the force is strongest
Pattern of the magnetic field
3. lines of force extend between the North and South poles because they attract each other
Pattern of the magnetic field
4. lines push away (repel) when like poles are facing each other
Pattern of the magnetic field
5. when two manets are placed close together, the lines of force show an interaction between them
What types of things can be made into temporary magnet?
things made of iron, steel and nickel can be made into temporary magnets.
How can you make a temporary magnet?
By rubbing a real magnet against the metal of a short period of time.
Does a temporary magnet hold magnetic force for very long?
NO
