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.
What else can I help you with?
How could a student use a magnet to indicate that combining iron an sulfur to produce the mixture of iron and sulfur is a physical change?
A mixture of iron and sulfur can be separated using a magnet- the iron will be attracted to the magnet, sulfur will not. Not the that the iron could be coated with sulfur powder so an extra step is required to remove it.
Is heating a bar magnet chemical or physical change?
Heating a bar magnet is a physical change because the magnet does not undergo a chemical reaction. The heat energy causes the atoms in the magnet to vibrate, which disrupts the alignment of the magnetic domains within the magnet, thereby reducing its magnetic strength.
Is picking up iron filings with a magnet a chemical reaction?
No, a chemical reaction is when the atoms are not mixed together but chemical bonded together. You know when a chemical reaction has happened when you can smell, hear or see things reacting.
Iron filings could be separated from sand using?
a magnet. The magnetic properties of iron allow it to be attracted to a magnet, making it easy to separate from non-magnetic substances like sand.
Is melting iron physical change or physical property or chemical change or chemical property?
Melting iron is a physical change because it does not alter the chemical composition of the iron. It is a change in state from solid to liquid without forming a new substance.
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) .

Jim drops an iron magnet during a chemistry lab experiment and she finds that it is no longer magnetic so what has happened in terms of its properties?
The iron magnet lost its magnetism, possibly due to undergoing a physical change that disrupted its magnetic alignment. This change could have disrupted the magnetic domains within the iron, causing it to no longer exhibit magnetic properties.
Is a magnet being used to remove iron shaving from dirt is an example of a chemical change?
It is a physical process. Not really a change of any kind.
Is making iron from iron ore a chemical or physical change?
Preparation of pure iron from iron ores involve physical changes but also chemical changes.
Can salt and iron filings be separated by physical means?
Yes, salt and iron filings can be separated by physical means such as using a magnet. The iron filings will be attracted to the magnet, allowing them to be picked up while the salt remains in the mixture.
What is a example of a physical change of iron?
Melting is a physical change of iron.
How is iron gathered?
Iron is gathered by making use of the magnet. Iron is usually mined as iron ore. Since it is magnetic, a magnet is used to separate it from the other foreign particles.
What is the raw material required for making artificial magnet?
iron
Is separating iron filings from sand with a magnet is a physical process?
Yes.
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
