A compass magnet or a compass needle.
To determine the poles of a magnetized iron bar, you can use a compass. One end of the bar that attracts the north-seeking end of the compass needle is the north pole of the bar. The opposite end that attracts the south-seeking end of the compass needle is the south pole of the bar.
The 4 moveable joints are called the Ball-and-socket, Hinge, Pivot, and Gliding joints.
You can perform a simple test by bringing a compass close to the metal bar. If the compass needle moves or aligns with the metal bar, then the bar is likely a magnet. Another test involves observing if the metal bar can attract small metal objects like paper clips.

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 compass interacts with a bar magnet by aligning itself with the Earth's magnetic field. The needle in the compass is a small bar magnet that points towards the Earth's magnetic north pole. This alignment allows the compass to determine direction based on the north-south orientation of the magnet.
The 4 moveable joints are called the Ball-and-socket, Hinge, Pivot, and Gliding joints.
The compass needle is a magnet and as you have probably tried, a magnet will 'stick' to an Iron bar. Thus as you move the compass near the Iron, its magnetic field lines are bent by the Iron and become locally stronger than the field lines of the planet, deflecting the needle away from north.
When a compass needle is placed near a bar magnet, it aligns itself with the magnetic field created by the magnet. The compass needle is a small magnet itself, with its north pole attracted to the south pole of the bar magnet and repelled by its north pole. If the compass needle points south, it indicates that the bar magnet's south pole is near the compass's north pole, demonstrating the fundamental property of magnetic attraction and repulsion. Thus, the orientation of the compass needle reflects the magnetic field direction of the bar magnet.
