Is it possible to create a ball with a positive magnetic core and a negative exterior? And vice versa?
Alexandre said:First of all, you're using the wrong terminology. Magnets don't have negative or positive charges, they have north and south poles, that's very different from electric charges. You can have a positively or negatively charged particle but you can't have a north pole without having the south pole on the same object, in other words you can't have a magnetic monopole, if you break up a bar magnet into peaces every single one of them will have north and south poles. Field lines of magnetic field should be closed curves because otherwise it would violate Gauss's law for magnetism (which states that divergence of magnetic vector field is zero).
I think it's impossible to create a perfectly shaped sphere with magnetic field lines uniformly pointing outwards everywhere on its surface.

A positive/negative magnetic ball is a small spherical object that contains both positive and negative magnetic poles. This allows the ball to attract and repel other magnetic objects, giving it a unique range of motion and properties.
A positive/negative magnetic ball is typically created by manipulating the properties of a material such as iron or steel. By heating the material and exposing it to a strong magnetic field, the particles within the material align in a way that creates both positive and negative magnetic poles.
A positive/negative magnetic ball can be used in a variety of ways, including as a toy for entertainment, as a stress-relieving tool, or as a teaching aid for demonstrating the properties of magnetism. It can also be incorporated into more complex devices, such as magnetic levitation systems.
While a positive/negative magnetic ball is generally safe to handle, it is important to keep it away from electronic devices, credit cards, and other magnetic-sensitive materials. Ingestion of multiple magnetic balls can also be dangerous, as they can attract and cause damage to internal organs.
Yes, the magnetic properties of a positive/negative magnetic ball can be changed by exposing it to a strong magnetic field in the opposite direction. This can effectively demagnetize the ball and make it lose its magnetic properties.
