A north pole will attract a piece of unmagnetised steel?
Only by inducing a magnetic field within the "unmagnetised steel".
What is special about the atoms in magnetic materials?
It's because the protons spin around the atom making a field of electricity.
What is the difference between a weakly magnetised nail and a strongly magnetised nail?
The strong magnetised nail will pick up more paper clips than the weak magnetised nail.That is because the strong magnetised nail is getting more strength and that means that the weak magnetised nail is getting less strength.in a steel nail there are these things called domains, in a weakly magnetised nail some of them will be pointing north, south, east and west, but however in a strongly magnetised nail all the domains will point to north.
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 the melting point of solid steel beams?
Technically, solid steel beams do not have a melting point, as they will not completely melt. Even when faced with temperatures of 1800 degrees Fahrenheit, they mainly corrode.
What is the difference about the domains in a magnetised steel bar and one that is unmagnetised?
The difference is the domains are facing in random directions in the unmagnatised and in the magnatised they are all facing the same way!

What is the diffrent between a magnetised steel nail and an unmagnetised steel nail?
what is the diffrence between a magnetised nail and a unmagnetised nail
Will the north pole of a magnet attract a peice of unmagnetised steel?
That depends on the steel. If it is a ferrous steel the magnet (either North or South) will attract it - If it is a a stainless steel that is austenitic steel it will not.
What can happen when you rub a magnet on a paper clip?
A paper clip is made up of iron or steel. It consists of particles called domains which are randomly arranged. When a magnet is rubbed on a paper clip, the domains arrange themselves in one direction. Thus it gets magnetized and behaves as a magnet.
Why is magnet unable to stick to a stainless steel refrigerator?
If a magnet doesn't stick to a material, that means that the material is non-magnetic. Every individual atom is a magnet, but in a magnetic material, there are groups of atoms (called "magnetic domains") that have their magnetic directions aligned. An outside magnetic field in such materials will align some of the magnetic domains in the direction of the magnetic field.
Is magnetizing steel a chemical or a physical?
physical, just the aligning of magnetic domains what were previously random in orientation.
What is special about the atoms in magnetic materials?
It's because the protons spin around the atom making a field of electricity.
Will a magnet attract steel paper clip?
Yes, this is true because in magnet, there are many small domains which all point the same way... this makes a magnet wot it is. the reason that a papa clip will attract to a magnet is because of all the domains (tiny magnets) inside swerve around when they feel the pulse of the magnets field.. by hazap ........... .......... brap brap!
What is magnetisation?
it is the force experienced by a north pole of strength 'p' placed at a distance 'd' meters from another pole of strength 'm'in a medium of relative permeability.in a steel nail there are these things called domains, in a weakly magnetized nail some of them will be pointing north, south, east and west, but however in a strongly magnetized nail all the domains will point to north.
What is magnetising force?

Is magnetizing steel a physical change or chemical change?
physical, just the aligning of magnetic domains what were previously random in orientation.
