I guess the easiest way to make it turn quite freely is to can hang it from a string.

Horseshoe, Bar, U, Ring, Circle, etc.
The largest Roman numeral number that can be made without using a bar is 3,999, which is represented by the letters MMMCMXCIX.
A rectangle magnet is commonly known as a bar magnet. It has a rectangular shape with a north and south pole at each end, producing a uniform magnetic field around it. Bar magnets are often used in various applications, including compasses, magnetic closures, and educational demonstrations of magnetism.
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 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.
The movable bar in a compass is called the compass needle. It is typically a thin magnetized bar that aligns with the Earth's magnetic field to indicate direction.

The north end of a compass needle would point toward the north pole of a bar magnet.
Well there isn't any positive or negative on a magnet. But to find North and South, you can suspend a bar magnet on a string and see which way it points, or use a compass. Remember that the North Magnetic Pole defines what Magnetic North is, and on a compass or a bar magnet the SOUTH magnetic pole point at it.
When you move the bar magnet around and above the compass about one foot away or farther, the compass needle will not be affected by the magnetic field of the bar magnet. The influence of the magnetic field decreases with distance, so at one foot or more away, the compass needle will remain pointing north as it is not close enough to be affected.
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.
The small bar magnet has a stronger magnetic field, at least at short distances.
Fill the container about half full of water. Float a leaf on the surface of the water, and float the needle on the leaf. That'll be a beautiful demonstration. I think I'll make one, and I thank you for the idea.
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.
