Magnets and Magnetism
Chapter 16, Section 1
Standard: 12.2: Describe the basic principles of an
electromagnet
Properties of Magnets
◼Any material that attracts iron or things
made of iron is called a magnet.
◼All magnets have two poles.
◼Magnets exert forces on each other and
are surrounded by a magnetic field.
Magnetic Poles
◼ Magnetic poles are points on a magnet that have
opposite magnetic qualities.
◼ The North pole of a magnet that points to the
north .
◼ The South pole points to the south.
◼ Magnetic poles are always in pairs.
Question:
◼What is a definition of a magnet?
Any material that attracts iron or metals
◼What are magnetic poles?
Points on a magnet that have opposite
magnetic qualities
Magnetic Forces
◼ Each magnet exerts a magnetic force on the other
magnet.
◼ These magnetic forces result from spinning
electric
charges in the magnets.
◼ The force can either push the magnets apart or pull
them together.
◼The magnetic force is a universal force.
◼Like poles repel, and opposite poles attract.
Question:
◼What can a magnet do?
Exerts a magnetic force on the other magnet
◼How do the poles behave?
Like poles, repel and opposite poles attract
Magnetic Fields
◼ A magnetic field exists in the region around a
magnet in which magnetic forces can act.
◼ These lines map out the magnetic field and are
called magnetic field lines.
Fill in the Blanks!
◼The closer together the field lines are,
stronger the magnetic field is.
the _________
◼Where do you think the magnetic force
is the strongest?
At the poles.
Put it Together… In the space provided on your
manual, do the following.
1. Write a one sentence summary that captures the lesson.
2. Draw a picture of a compass.
Show the magnetic field around it.
Identify the direction of the magnetic field with arrows.
3. Magnetic skill sheet
If you do not finish these 3 items in class,
it is HOMEWORK due Monday.
