WebSep 12, 2024 · Lenz's Law. The direction of the induced emf drives current around a wire loop to always oppose the change in magnetic flux that causes the emf. Lenz’s law can also be considered in terms of conservation of energy. If pushing a magnet into a coil causes current, the energy in that current must have come from somewhere. WebFeb 3, 2011 · That's like asking someone to calculate 2+3 using partial differential equations. Fluxes and currents are representations. Any quantity that can be written as the surface intergral of a vector field is called the flux of that field through that surface. So, for instance, the electric current I, is the flux of the current density vector J.
