... (easy-axis) and ay < ax (hard-axis) aligned to the reference frame. We apply an external magnetic field fixed (in the direction of the y-axis, ϕ = π / 2 ) and an external electric field with intensity varying within a given range (in the fixed direction ϕ = π / 4 ) [12].

... make them work properly, the magnetic field on them must be less than 0.1G. Therefore, they are enclosed with Mu-metal, which has a very high magnetic permeability and is very good at screening DC magnetic field. Also, in order to ensure the magnetic field is small enough, the detectors are placed i ...

... Maxwell’s equations provide the curl and divergence of the electric fields and magnetic fields in terms of other things. The reason this is useful is that Helmholtz’s Theorem tells us that if we know the curl and the divergence of a vector field, we can explicitly calculate the field itself, and fur ...

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.
