Why heat demagnetised the steel?
A piece of metal can be magnetized if the atoms of which it is composed are magnetic, and they have aligned their north-south poles to point in the same direction. Heat increases atomic vibration and will cause these atoms to lose their alignment and point in all different directions, so that their atomic magnetic fields will not combine to form one large magnetic field.

How do you spell demagnetised?
In Australia and the UK, you would spell it "demagnetised". In the US, you would substitute a 'z' - "demagnetized".
How does heat affect a magnet?
A permanent magnet (i.e. not an electromagnet) will be demagnetised by heating it.

How does soft iorn is different from hard iron?
That depends on what you mean - soft iron is usually the name given to iron that is easily magnetised and demagnetised. In which case it is usually very pure. Mecahnically soft and hard irons have different crystal structures and trace impurities, although iron is more correctly known as steel when it is anything but 100% pure iron.
Why is soft iron named as soft iron?
Soft iron does not retain magnetism. It can be magnetised and demagnetised quickly and easily. Used as a core for transformers. 'Soft' probably relates to it's submission, when exposed to magnetism. It 'gives in' without too much fuss.
How does demagnetisation of a magnet occur when you keep similar poles together?
WHEN A MAGNET IS DROPPED OR HAMMERED, VIBRATIONS CAUSED BY THE IMPACT ON THE MAGNET RANDOMIZE MAGNETIC MOLECULES and disturb the pattern of molecules of the magnet as a result magnet looses its magnetic force and becomes demagnetised.
Why can a magnet be demagnetised by hammering it?
because when it is hit with a lot of force some of the little invisible magnets inside or the domains are thrown off and they don't attract to each other as much.
How can iron be demagnetized?
an iron can be demagnetised by ;-hammering it while facing east _west direction -hitting it hard on the ground -connecting it into an ac current while facing the east _west direction .
What role is played by molecular magnets to magnetize and demagnetize bodies?
The relative coercitivity of a material helps to magnetize and demagnetised a substance. If the coercitivity id low then the material can be easily demagnetized and vice versa. A substance can be magnetized by creating magnetic filed of opposite charges and demagnetized by creating same filed of charges.
Why heat demagnetised the steel?
A piece of metal can be magnetized if the atoms of which it is composed are magnetic, and they have aligned their north-south poles to point in the same direction. Heat increases atomic vibration and will cause these atoms to lose their alignment and point in all different directions, so that their atomic magnetic fields will not combine to form one large magnetic field.
What is a magnet that consists of a piece of iron or steel inside a coil of current carrying wire and uses electricity to produce magnetism?
its called an electromagnet... the current running around the core- i.e. the iron or steel piece, alligns the poles of the core according to the current flow. hence after alignment the core acts as a magnet, but when current flow is stopped, the core gets demagnetised. electromagnets have very important applications.
Can objects be demagnetized?
yes, an object can be demagnetized by 3 ways:hammeringheatingalternating current method
