Magnetic erasing of a computer disk is a physical change. The polarity of the molecules in the storage media is altered, but the material retains the same composition so it is NOT a chemical change.

Is a magnet earaseing a computer disk a chemical or physical change?
The answer is physical:)
Is heating a bar magnet chemical or physical change?
Actually itz just a temporary physical change.........as u dont add on subtract anything frm the magnet exept heat.....,heat does not effect chemical properties of an iron magnet..
Is separating sulfur and iron with a magnet chemical or physical change?
This is not a change at all. However it is physical when you use a magnet to physically seperate (by manetic force) .

It is a physical process. Not really a change of any kind.
Is magnet a forcewhy?
No, a magnet is a physical object. However, a magnet can EXERT a force.
Is making iron into a magnet a physical change?
To make an iron bar into a magnet you need to get a bar magnet and stroke the iron one way when you get to the end of iron take the magnet off and jump it back to the start and stroke repeat this several times and your bar will soon become magnetic. This is only temporary, therefore the iron will become normal after the magnetic field rubs off. This means that making iron into a magnet is indeed a physical change.
Is magnetic attraction a physical or chemical change?
Magnetism is a physical property that is mediated by magnetic fields.The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, a material's magnetism doesn't change the composition, and doesn't involve a chemical reaction.
Is magnetizing steel a chemical change or physical change?
physical, just the aligning of magnetic domains what were previously random in orientation.
Is magnetism a physical change?
yes because any that you do in magnet it is magnet again'
Does temperature affect the strength of a magnet is it chemical science?
NO!!! the strength of magnet is not affected by temperature
Is mercury attracted to a magnet?
Mercury, although it does posses some interesting physical and chemical properties, should not be attracted to a magnet. It is considered to be diamagnetic, which means it would actually oppose a magnetic field and repel. If you have more questions on mercury or diamagnetism.
