Gravitoelectromagnetism, abbreviated GEM, is a set of formal analogies between the equations for electromagnetism and relativistic gravitation. More specifically, it is an analogy between Maxwell's fi

Maxwell's equations are a set of coupled partial differential equations that describe how electric and magnetic fields are generated by electric charges and currents. Together with the Lorentz force l

In a geomagnetic storm, solar wind plasma impacts Earth's magnetic field causing a time-dependent change in the field, thus inducing electric fields in Earth's atmosphere and conductive lithosphere which can destabilize power grids. (Not to scale.)
Magnetic-core memory (1954) is an application of Ampère's circuital law. Each core stores one bit of data.
