understand that you are asking how to make a magnet from an iron strip. Here is a simple method to do so:
Take a rectangular piece of iron and place it on a table.
Take a bar magnet and place one of its poles near one edge of the iron strip.
Without lifting the bar magnet, move it along the length of the iron strip till you reach the other end.
Now, lift the magnet and bring the pole (the same pole you started with) to the same point of the iron strip from which you began.
Move the magnet again along the iron strip in the same direction as you did before.
Repeat this process about 30-40 times.
Bring a pin or some iron filings near the iron strip to check whether it has become a magnet. If not, continue the process for some more time.
This process works because the magnetic field of the bar magnet induces a magnetic field in the iron strip. Repeatedly moving the magnet along the iron strip in the same direction causes the magnetic domains in the iron to align in the same direction, creating a magnetic field in the iron strip 123.
