View Full Version : Connecting alot of south poles in the middle of a sphere.

I got a question.

What would happend if you connected alot of coils from the centre of a sphere (coils would be the radius of the sphere) (almost like a star if you draw it). Then you add Voltage/Current to the coils. And evey coils are powered with southpole in the centre of the sphere.

Im not talking about few coils... but tremendous amount of em ;)

I know the southpoles are trying to push each other away. But they are all forced to be stuck in the centre makeing the magnetic field crash into eachother.

Anyone knows what would happend if something like this was created? nothing would happend? or perhaps something fun would happend? :p

You are talking about attampting to make a north magnetic pseudo-monopole (not the monopoles of quantum physics). This has been thought of many times, and attempted. Unfortunately, the math and the actual results agree. The net result of this configuration is null. The magnetic fluxes are cancelled out and the thing just sits there like a lump.

I think the thing would try to break itself apart, due to magnetic forces.

This wouldn't create a true magnetic monopole, either. Some field lines would still fit through the gaps between the coils, no matter how tightly you packed them.

When I was young, before the internet and college, I had this brilliant idea. I would put a bunch of permanent magnets in a spherical arrangement, all of one pole toward the center, and figured it would "float" over another set of magnets arranged in a bowl shape. It would be so cool!

- It tried to tear itself apart.

- I used a lot of glue.

- The result was no detectable magnetic field outside the sphere.
