MAGNETISM REVIEW
ANSWERS UP!!
WHAT IS THE NAME OF THE
MINERAL DISCOVERED BY THE
GREEKS WITH MAGNETIC
PROPERTIES?
A COIL OF WIRE THAT PRODUCES A
MAGNETIC FIELD
A DEVICE THAT USES MAGNETISM
TO CHANGE KINETIC ENERGY INTO
ELECTRICITY
A PERMANENT MAGNET MADE OF
IRON, NICKEL AND COBALT OR
ALLOYS OF THESE
A DEVICE THAT CHANGES
ELECTRICAL ENERGY INTO MOTION
A DEVICE THAT CHANGES THE
VOLTAGE OF A CURRENT
THIS OCCURS WHEN AN ELECTRIC
CURRENT IS PRODUCED BY A
CHANGING MAGNETIC FIELD
LIST 2 WAYS A MAGNET WILL LOSE
ITS MAGNETIC FORCE.
WHAT ARE 2 WAYS YOU CAN
MAGNETIZE AN OBJECT?
WHAT ARE 3 PROPERTIES ALL
MAGNETS MUST HAVE?
WHEN A MAGNET IS BROKEN IN
HALF, WHAT FORMS?
A COMPASS NEEDLE POINTS NORTH
BECAUSE…
WHERE IS THE MAGNETIC FIELD
THE STRONGEST?
THE AREA AROUND THE MAGNET IS
THE…
WHY DOES THE EARTH HAVE A
MAGNETIC FIELD?
LIST 2 WAYS TO INCREASE THE
STRENGTH OF AN
ELECTROMAGNET.
FINAL JEOPARDY! PLACE YOUR

WHAT DO WE CALL THE REGIONS IN THE
MAGNETIC FIELD WHERE THE CHARGED
PARTICLES FROM THE SUN ARE TRAPPED?
