Alwin puts magnets in her sewing
kit together with the needles.
• What was her purpose of putting
the magnet in it?
• What is the importance of the
magnet in her sewing kit?
65. Here are the other benefits of
using magnets:
• They are used to construct the electrical
motors and the generators which convert
the electrical energy into mechanical
energy and vice versa.
• They are also used in the speakers which
can convert the electrical energy into
sound energy.
66. • They are used in the electrical bells.
• They are used in the Maglev trains. In the
Maglev trains, the super conducting
magnets are used on the tracks on which
the train floats. These types of the trains
are working on the repulsion force of the
magnets.
• They are also used to sort out the
magnetic and non magnetic substances
from the scrap.
67. • They are used in TV screens, computer
screens, telephones and in tape
recorders.
• They are used by the candy or cold drink
vendors to separate the metallic cap from
the lots.
• They are used in cranes.
• They are used in the refrigerators to keep
the door close.
68. • The most important use of the magnet is
the magnetic compass which is used to
find the geographical directions.

Materials are put on a conveyor belt that is
spun by magnetic wheels.
3. Magnetic separation technique can also be
useful in mining as it is attracted to a
magnet.
73. 4. Magnetic separator is also used in
milling. It removes metal species in
