... The loop has to be “pulled” out of the magnetic field, so there is a pulling force, which does work. The “pulling” force is opposed by a magnetic force on the current flowing in the wire. If the loop is pulled “uniformly” out of the magnetic field (no acceleration) the pulling and magnetic forces ar ...

Controlling the dark exciton spin eigenstates by external magnetic field
... Figure 1(b) presents an intuitive geometrical interpretation for the angle θB and the DE Bloch sphere. Since in the Faraday configuration the magnetic field direction is aligned with the direction of the |+2 spin state, it follows that π/2 − θB is the angle between the Bloch sphere eigenstate axis ...

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.
