# If Magnetic Monopoles Would Have Existed. How Would Gauss' Law Of Magnetism Be Modified?

A magnetic monopole needs to be analogous to an electric monopole. A stationary electric monopole produces no magnetic field, so that a magnetic monopole can produce no electric field. Therefore Gauss’s law for electricity is unaffected,

∇ . E = $$\frac{\rho}{\varepsilon_{0}}$$

Gauss’s law for magnetism takes an analogous form,

∇ . B = μ0ρm
