Magnetic Field Distribution

Give us a case. Tell us what the general sizes are, what the material is, and what the general magnitude of the current is.

Ok. Here goes. Imagine you looking at the rod from its transverse c/s. If the current is going in it away from you, the North Pole is at the far end and the mgtc field surrounds the rod in a circular manner with lines of force in clockwise direction.... Hope this helps.

I'm a little unclear about what you describe. Is this an invention where you want to not reveal details?

It appears, from what I think I understand, that you have the elctric and magnetic fields mixed up. Here's a link that might help.

ok in that case the closing face of the rod becomes my north and the closing face of the disc becomes my south. for more clarity i will give u the picture

your are passing current through coil wound around metal rod with disc at one end , or current through metal rod with disk , this remind me of alluminium disc rotating in magneticfield generated by core wound by coil just as found in energy meteres to calculate power consummed , and some people using powerfull magnet to slowdown the rotation (stealing???)

the case is passing the current through metal rod with disk. i want to know the resulting pole position. i suppose it is similar to what you thought, but not the case of power theft. just clarifying my doubt. thats all

If the curent goes through a rod the generated magnetic field lines are circles around the rod so that you cannot have a N or S pole on the rod.

Only if the curent goes in a coil "around " the rod then magnetic field lines which are around the conductors of the coil will generate a manetic dipole with your rod if it is of the right material.

In the wattmeters there is a permanent magnet which generates a field perpendicular to the disc surface. The curent goes in radial direction through the disc and the interaction curent-field generates the movement.

Follow wht an other comment said look in a book about magnetics ther are several in very abordable prices.
