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.
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.
Bar magnets interact with iron filings by creating a magnetic field that causes the iron filings to align along the magnetic field lines, forming patterns that show the shape and direction of the magnetic field.
First sprinkle iron filings on a glass plate well scattered. Now place a bar magnet under the surface of the glass plate and give light jerks continuously to the plate. Gradually the iron filings would be arranged in curved lines. More filings are found concentrated near by the poles. These curved strutures stand for the magnetic lines in the vicinity of the magnet. Actually magnetic lines of force are only imaginary lines.
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.
The Earth's magnetic field is generated by the movement of molten iron in the outer core, while a bar magnet is a permanent magnet made of a material that can be magnetized, such as iron. The Earth's magnetic field is much weaker and more complex than that of a bar magnet, which has a consistent north and south pole.

Aluminum and iron can be differentiated because iron is magnetic and aluminum is not. To separate them, expose the filings to a magnetic source and the iron will separate.
by using a bar magnet,because iron fillings are magnetic and hence it gets attracted to that bar magnet
The iron filings align along the magnetic field lines when sprinkled over a bar or horseshoe magnet. This creates a visual representation of the magnetic field around the magnet. The filings cluster at the poles of the magnet where the magnetic field is strongest.
They tend to align along the magnetic field lines.
The poles of a magnet are the ends of the core of the magnet, where the lines of force emerge. An experiment with iron filings shows the lines of force, by putting a sheet of paper over the magnet and sprinkling fine iron filings. This is an easy thing to do at home. For a bar magnet the poles will be at opposite ends. If you have two such magnets you can experiment and find that like poles repel, opposite poles attract.
spread out from one pole and curve around to the other
becouse at north &south poles the pole strength is more than other part of bar magnet so attraction is also more at poles Theoretically, magnet's lines of force - as evinced by the iron filings - encompases all universe, but, nonetheless, they meet together at the magnet's poles
Iron filings can be used to map the magnetic fields on a magnet by putting pieces of irons on a piece of paper,pass the magnet under the paper,and the side which has more iron filling is the north pole and the side which has less iron filling is the south pole.

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.
