Gauss’ Law for Magnetic Fields The simplest magnetic structure that exists is the magnetic dipole. Magnetic monopoles do not exist (as far as we know). We know how to apply Gauss’ Law to the electric field: Φ E = I ~ E · d ~ A = q encl 0 In a closed loop, where Φ B is changing, we get an induced ~ E : Maxwell’s Law of Induction: I ~ B · d ~ s = μ 0 0 d Φ E dt
