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.
You can also change it into an electromagnetic by rapping a coiled wire tightly around it and send the current through the wire. The current will induce a magnetic field, causing the iron to magnetize temporarily.
Lastly, you can heat the iron in a powerful solenoid field. As the iron heats up the regions become "free" to orientate with the field. The iron has to be heated to a orange/yellow glow before this is largely effective. The iron should then be allowed to cool in the presence of the field.
What else can I help you with?
How can you tell the difference between a bar of iron a bar of copper and a magnet?
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
Why is magnetism induced into an iron bar placed near a magnet?
When an iron bar is placed near a magnet, the magnetic field of the magnet aligns the magnetic domains within the iron bar. This alignment increases the overall magnetic field strength of the iron bar, effectively inducing magnetism in the bar.
You are given a small plotting compass and three grey metal bars one is aluminum one is iron one is magnet how can i identify each one?
The bar that affects the compass is the magnet, The bar that is attracted to the magnet is iron, and the bar that is not attracted to the magnet is aluminum.
How you separate a mixture of common salt camphor and iron filings?
by using a bar magnet,because iron fillings are magnetic and hence it gets attracted to that bar magnet
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.
Why the iron can make the magnet move?
Because anything that has iron is attracted to magnet so whether its not fully an iron as long as it has iron in it, it can make the magnet move or attract it
What type of magnet attracts to iron but not for a long time?
A temporary magnet, such as an electromagnet, can attract iron but only for a short period of time. This type of magnet requires an external power source to create a magnetic field, which can be turned on and off as needed.
How do you make an iron into a magnet?

How do iron filings interact with a bar magnet?
Iron filings interact with a bar magnet by aligning themselves along the magnetic field lines produced by the magnet. This creates a visible pattern that shows the shape and direction of the magnetic field.
How does a bar magnet interact with iron filings to demonstrate magnetic field lines?
When a bar magnet is placed under a sheet of paper with iron filings on top, the iron filings align along the magnetic field lines of the magnet, showing the direction and strength of the magnetic field.
Earth's magnetic field can make a magnet out of an iron bar by causing the magnetic domains to?
It lines up in the same direction :)
How can you magnetise an iton needle permanently using a strong bar magnet?
Rub the iron needle along one direction on the strong bar magnet repeatedly until it becomes magnetized. Make sure to always rub it in the same direction to ensure a consistent magnetic field. This process aligns the magnetic domains within the iron needle, causing it to become permanently magnetized.
