Ten Facts about Magnets
(from the book Driving Force)
-
North poles point north, south poles point
south.
-
Like poles repel, unlike poles attract.
-
Magnetic forces attract only magnetic
materials.
-
Magnetic forces act at a distance.
-
While magnetized, temporary magnets act
like permanent magnets.
-
A coil of wire with an electric current
flowing through it becomes a magnet.
-
Putting iron inside a current-carrying
coil increases the strength of the electromagnet.
-
A changing magnetic field induces an electric
current in a conductor.
-
A charged particle experiences no magnetic
force when moving parallel to a magnetic field, but when it is moving perpendicular
to the field it experiences a force perpendicular to both the field and
the direction of motion.
-
A current-carrying wire in a perpendicular magnetic
field experiences a force in a direction perpendicular to both the wire
and the field.
