Ok, true, my bad - forgot to put that bit in. The magnetic field is uniform. It is also horizontal.
Think of the curved portion of the wire (elevated, not levitated, along the sphere) then the magnetic field running uniformly beneath it in a horizontal plane. In other words, look at this, +...
Ok, just a quick question. I'm working through a problem in my physics book and I am asked to find the magnetic force on a current carrying wire that runs along the equator of a sphere. So the wire is not straight, but curves along with the sphere, off the surface of it (not levitating).
My...
Here the extra credit question I'm stuck on:
A square loop (perimeter of 4L and hinged along one side) is made of a wire that has a mass per unit length of 0.1000 kg/m and carries a current of 5.000 A. A uniform magnetic field of 10.00 mT directed perpendicular to the hinged side exists in...
