Each half would have a north pole and a south pole.
Move towards the U magnet so that the poles attach.
A bar magnet creates an invisible magnetic field around it, and magnetic metals such as iron are attracted to the magnet. Any metal structure is then included in the magnetic field lines. For iron filings on the sheet of paper, they will group into clusters near the poles, and also form an oval pattern along the length of the magnet, representing the magnetic field lines. The field is bulged outward nearest the center of the magnet's length. This displays the approximate two-dimensional shape of the three-dimensional magnetic field. For a picture, see the related link.
A horseshoe magnet has two poles that are close together, which concentrate the magnetic field. A U-shaped magnet has a similar shape to a horseshoe magnet, but with one pole at each end, providing a more uniform magnetic field. A rod magnet has a simple cylindrical shape and its magnetic field is spread out along its length.
When iron fillings are sprinkled near a magnet, they will be attracted to the magnet and align themselves along the magnetic field lines. This occurs because the iron fillings are small magnetic dipoles with north and south poles that align with the magnetic field of the magnet.
because the magnet causes particles called electrons in the atoms of the nail to align along the magnet's lines of force. The atoms with aligned electrons then act like tiny bar magnets themselves.
When a bar magnet is held in the air by a string, it will align itself along the Earth's magnetic field lines. One end of the magnet will point north while the other end will point south. This behavior is due to the interaction between the bar magnet's magnetic field and the Earth's magnetic field.
Move towards the U magnet so that the poles attach.
They tend to align along the magnetic field lines.
Iron filings are attracted to a magnet and align themselves along the magnetic field lines, forming a pattern that shows the shape and direction of the magnetic field.

A magnet with many lines of force refers to a strong magnetic field that is densely packed with magnetic field lines. These field lines represent the pathways along which the magnetic force acts, flowing from the magnet's north pole to its south pole. The density of these lines of force indicates the strength of the magnet's 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.
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.
A magnetic compass or iron filings can be used to show the magnetic lines of force. When a compass is placed near a magnet, the needle aligns along the magnetic field lines, indicating their direction. Iron filings sprinkled near a magnet will also align along the magnetic field lines, providing a visual representation of the magnetic field.
A bar magnet interacts with a compass by aligning the compass needle along the magnetic field lines of the magnet. This causes the compass needle to point towards the North Pole of the magnet, allowing the compass to indicate the direction of the magnetic field.
A horseshoe magnet has two poles that are close together, which concentrate the magnetic field. A U-shaped magnet has a similar shape to a horseshoe magnet, but with one pole at each end, providing a more uniform magnetic field. A rod magnet has a simple cylindrical shape and its magnetic field is spread out along its length.
You can show the magnetic field around a magnet by using iron filings. Sprinkle the iron filings on a piece of paper or a glass surface placed over the magnet. The iron filings will align along the magnetic field lines, making the field visible.
