Magnet ABCs
What is a magnet?
any material that attracts iron and materials that contain iron
The attraction or repulsion between magnetic poles is called this.
Magnetic Force
Opposite poles (North and South poles)
What is shown? (See picture 1)
Magnet
A magnet is considered this?
Force
What can a magnet can attract or repel?
other magnets
The area of magnetic force around a magnet is known as this.
Magnetic Field
The same poles do this to each other.
Repel against each other
What is shown? (See picture 2)
Magnetic Field Lines
Magnetism attracts to other objects without needing to touch the other object, similiar to this force we have studied?
Gravity
These poles are located on a magnet.
North and South Poles
The mineral in magnetic rock is this.
Magnetite
Unlike poles do this to each other.
Attract to each other
Which diagram (A or B) shows attraction?
Diagram A
Iron
Where the strongest magnetic force occurs on a magnet.
Magnetic poles
We can't see this area around the magnet.
Magnetic Fields
How do you determine which way to rotate the magnet?
Arrows point away from the NORTH pole and towards the SOUTH pole.
Which diagram (A or B) shows repulsion?
Diagram B
Magnets do not attract all of these.
Metals
Magnetic field lines leave from THIS pole and loop around the magnet towards this THIS pole.
What do we need in order to visualize a magnetic field?
Need many small moveable items (like iron filings) that attract to magnets.
Maglev trains use magnets to elevate trains so they never touch the tracks. The poles of the magnets on the trains facing the magnetic poles of those on the track MUST BE what?
the SAME, so they REPEL each other
In diagram B, which poles are facing each other in each of the magnets?
Left magnet - South and North
Right magnet - North and South
Magnets will do this to the same pole of other magnets.
Repel
