What can be magnetised?
ferro magnetic substances can be magnetised. but it is not necessary that all the Ferro magnetic substances can be permanently magnetised. it depends on the alignment of domains in the substance.for example wrought iron can be magnetised permanently but soft iron can only be magnetised temporarily(Electro Magnets).
Is steel atracted to a magnet?
Contrary to popular belief, most metals cannot be magnetised. The only common metals that can be magnetised are iron, cobalt and nickel. Mild steel, an alloy that contains over 98% iron, can also be magnetised because of its high iron content. Some steels, such as some stainless steels, have larger percentages of other metals which prevent them from being magnetised the same way.
Can all metals be magnetised?
iron nickel and colbolt
Why do steel and iron attract each other?
Metals can be magnetised which can produce an attractive force.
Magnetism is an example of a mass property?
Magnetic fields are generated by electric current, hence magnetic forces would be an electrical property, not a mass property. Gravity is the force that exists between two masses.However, materials have magnetic properties based upon their chemical composition, for example iron metal maybe magnetised, that is a property of that material (note material, not mass).A piece of iron may be magnetised regardless of its mass (1kg or 1g or 1 tonne), as magnetism is not mass related.However, I believe what you are trying to ask is whether magnetism is a property of the material, not the mass, in which case, yes, it is a property of the material, based upon its chemical composition.
Why is iron a better core material than steel?
Because steel remains magnetised
Is there a limit to how strongly magnetised an iron nail can get?
Yes, every material has its limit in this respect.
How is the arrangement of domains different in a magnetised and a non magnetised piece of iorn?
In an unmagnetised piece of iron, these magnetic domains are arranged randomly and point in lots of different directions - they cancel each other out. In a magnetised piece of iron, all these domains point in the same direction. This makes one end of the magnet act as a north pole and the other end act as a south pole. The better the domains are aligned, the stronger the magnet. Bye bye!
Can iron be magnetised?
Iron is naturally magnetized.

What object that attracts iron?
none of them. iron can be magnetised but the material itself is not magnetic
What happens to the domains in a piece of iron when it becomes magnetised?
The iron automatically divides into domains separately. It does not exist in a state when magnetization occurs in the same direction, in the entire material. This is to minimize its internal energy.

Why a coil of wire with a direct current passing through it will magnetise a piece of iron?
The coil would act as if a bar magnet inserted along its axis. So any iron material inserted gets magnetised.
Can all metals be magnetised?
iron nickel and colbolt
What type of material is used for making temporary magnet?
An electo-magnet has an iron core wrapped round with wire coils. When electricity is passed through the coils, the iron core become magnetised, until the electricity is switched off.
Why do steel and iron attract each other?
Metals can be magnetised which can produce an attractive force.
