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.

that magnet can be
use in separating
mixtures in our daily
living

the floor a open pack
of pins. What is the

from using
magnets in
separating
mixtures? How?

72. Draw happy face that show the benefits
from separating mixtures using magnet
and sad face if it is not.
1. Separating iron nails from glass chippings
and separating iron paper clips from saw
dusts.
2. Magnetic separators are used in factories.
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
wheat, in order to ensure safety at
work. To remove metal content from
wheat to protect other machines
safety
5. Remove metal powder mixed in flour
during milling process and to ensure
product purity, magnetic separation is
needed before finished product
packaging.
