circular because you can find small circular magnets called "rare earth super magnets" at the store called princess auto
There are some variables like what the magnet is made of and how it was initially magnetized. If a bar magnet is bent into a horseshoe shape to make a horseshoe magnet, the magnetic field will be more dense (stronger) across the gap of the horseshoe magnet than it would have been anywhere around the bar magnet from which it was made. And since magnets are strongest at their poles, horseshoe magnets can use both their poles at once while bar magnets can only use one pole at a time.
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.
by keeping another magnet or attractive force
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.
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center
Not necessarily.
No, electromagnets are stronger than bar magnets.
No. The magnet has a sort of symmetry, in the sense that its two sides are "equal but opposite".
a electromagnet is bigger than a bar magnet
A bar magnet attracts a paper clip with more force compared to a refrigerator magnet because the magnetic field of the bar magnet is stronger due to its design and material composition. The shape and alignment of the magnetic domains in a bar magnet allow for a more concentrated and powerful magnetic field, resulting in a stronger pull on the paper clip.
The small bar magnet has a stronger magnetic field, at least at short distances.

One key difference between a bar magnet and a horseshoe magnet is their shape. Bar magnets are long and rectangular, while horseshoe magnets are U-shaped. Another difference is their magnetic field strength, with horseshoe magnets typically having a stronger magnetic field at the poles compared to bar magnets.
The magnetic domains in a refrigerator magnet are laid down in parallel strips. They are also re-curved back on themselves so that the back side of the magnet has both north and south poles. If you put two refrigerator magnets back-to-back and move them around a little, it won't take long for you to "feel" the strips of magnetism. The common bar magnet have two simple poles at the ends.
They are bar magnet ,horse shoe magnet ,lime stone magnet.
The field strength is greater closer to the ends of the bar magnet than near the center.
The strength of a magnet, whether a ring or a bar, depends on several factors including the material, size, and shape. Generally, bar magnets can be designed to have stronger magnetic fields in specific applications, while ring magnets can provide a more uniform magnetic field. In practical use, the effectiveness of each type often depends on the specific requirements of the application, such as space constraints or the need for a concentrated magnetic field. Thus, it's not inherently about one being stronger than the other, but rather which is more suitable for a given purpose.
