... The direction would have to be East for the right hand rule, applied to the velocity and the magnetic field, to give the proper direction of force. 30. Determine the magnitude and direction of the force between two parallel wires 35 m long and 6.0 cm apart, each carrying 25 A in the same direction. ...

... Hint: Intuitively, the divergence of a vector field is a measure of the density of source/sink of the field. For reference, the electric field lines drawn in Fig. 2 will be those of a point dipole in the limit of distance between the two charges going to zero, keeping the magnitude of the dipole mom ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
