- Magnets should be kept in pairs with their unlike poles on the same side. They must be separated by a piece of wood while two pieces of soft iron should be placed across their ends.
- For horse-shoe magnet, one should keep a piece of iron across the poles.
Can magnet lose their properties write a few cautions while handling magnets Class 6?
Precautions in Handling Magnets
The magnets lose their
property of magnetism if they are heated strongly, hit with a hammer or dropped from a height
.
How magnets are kept safely?
Magnets are kept
in magnetic keepers when they are not in use
. The magnetic keeper is the pieces of soft iron and has a cardboard with one or two iron soft pieces. Two magnets are placed in such a way that their opposite poles are close to each other and then a soft iron keeper is attached with it.
How are magnets stored explain Class 6?
Bar magnets should be stored in pairs
, with Dropping from a height unlike poles alongside each other. A horseshoe magnet should be stored with a piece of soft iron kept across its poles.
What are the precautions to be taken while handling magnets?
- Always wear safety goggles when handling large magnets.
- Always wear gloves when handling magnets to prevent pinching.
- Children should NEVER be allowed to play with NEODYMIUM magnets.
- Keep magnets at least 20cm away from sensitive electronic and storage devices.
What are uses of magnet?

magnetic compass, doorbells, refrigerators
. Magnets are used in dynamos, motors, loudspeakers, microphones etc. Ceramic magnets are used in computers. Magnets are used in toys to give a magic effect.
What are the 4 properties of magnets?
- Magnets will attract ferromagnetic substances.
- Like poles of the magnet repel each other and unlike poles attract each other.
- A suspended magnet always comes to rest in the north-south direction.
- The poles of the magnet are in pairs.
Which is a natural magnet class 6?
Magnetite
is a natural magnet. Magnet attracts materials like iron, nickel, cobalt. These are called magnetic materials. Materials that are not attracted towards magnet are called non-magnetic.

What are magnetic keepers for Class 6?
Answer: A magnetic keeper is
a piece of wood or soft iron which is used in storing magnets
because bar magnets get demagnetised when the poles are left free for a long time. In order to preserve the magnetism of the magnets, a keeper is kept across a pair of bar magnets with unlike poles beside each other.
What is the role of magnet keeper?
A magnet keeper, also known historically as an armature, is a bar made from magnetically soft iron or steel, which is placed across the poles of a permanent magnet
to help preserve the strength of the magnet by completing the magnetic circuit
; it is important for magnets that have low magnetic coercivity, such as …
What are natural magnets?
Magnetite, also known as lodestone
, is a naturally occurring rock that is a magnet. This natural magnet was first discovered in a region known as magnesia and was named after the area in which it was discovered.
How do magnets help move a train?
In Maglev, superconducting magnets
suspend a train car above a U-shaped concrete
guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other. … Here, both magnetic attraction and repulsion are used to move the train car along the guideway.
What are 5 uses of magnets?
- Compass. A compass uses a magnet to direct its needle to the north pole.
- Mag-Lev Trains. …
- Vending Machines.
- Holding Things.
- Electric Motors.
What are Class 6 magnet types?
There are two types of magnets:
Natural Magnets are made up of magnetite
and are found in nature. Artificial magnets are prepared using various processes and with the help of iron. Examples of artificial magnets include bar, horse shoe, cylindrical, ball-end magnet etc.
What are bristles Class 6?
Bristles: Bristles are
hair like structure, connected with muscles
. The bristles help to get a good grip on the ground. ‘ Cavity: It is the hollow space or cavity in one bone, into which the other bone fits.
