Magnetic Monopoles in a Magnetic Universe

1984
Large scale coherence of a cosmological magnetic field, independently of its strength, is incompatible with any detectable monopole flux. Consequently, the controversial evidence1 of a coherent magnetic field up to a redshift z ≃ 2 infers the most severe cosmological bound on present number density (no) and fluxes (F) of magnetic monopoles: \( n_O < 2 \

Magnetism and Magnetic Fields

2012
The study of magnetism and magnetic fields readily follows the study of electricity and is normally a second-semester topic in a first-year physics course. One of the difficulties that a teacher may encounter is that students often confuse magnetic poles with electric charges.

Magnetism, magnetics and microstructure

Ultramicroscopy, 1992
Abstract The relationship between magnetism, magnetics, and microstructure is discussed from the viewpoint of three different theoretical techniques. A dynamic micromagnetic theory is used to show that hysteresis can be accurately predicted from structural properties without the need for adjustable parameters.
