This presentation considers a simple extension of the standard model to include magnetically charged particles that achieve their masses through a magnetic version of the Higgs mechanism. At energy scales that allow for the production of these particles, the evolution of the gauge couplings of the standard model changes dramatically and final states display significant contributions from CP-odd dynamics. Consistency of existing electro-weak phenomenology helps determine the properties and mass-scales associated with "magneto-weak" forces (that are actually quite strong). It can be argued that systems (neutrinos and antineutrinos carrying magnetic isospin) may display properties to the magnetic "monopole-molecules" observed in low-energy spin ices and could be a viable candidate for WIMP dark matter.
