# Vectorial equation of the Magnetic Field of a particle?

The same type of equation for Magnetic Field as these two are for the Electric and Gravitational Field:

Thanks.
Update: I feared that...
Is there any ideally simple equation, that relates the magnetic field vector to certain current variation, magnet or something similar?
Update 2: I'm not trying to solve a problem.
I'm just trying to define the magnetic field vector in the simplest way possible that let's me understand and predict most of the stuff related to magnetic forces.
