The basics about the direction of force and field comes from the “Fleming’s Left Hand Rule” and the “Maxwell’s Corkscrew Rule”. In addition to these the Lorentz force law, i.e. F=q[E+(vxB)] gives the force on a charge moving through a magnetic and electric field [Neglect E if electric field is absent.]

What is the differential form of Gauss law?
Differential form of Gauss law states that the divergence of electric field E at any point in space is equal to 1/ε0 times the volume charge density,ρ, at that point. Where ρ is the volume charge density (charge per unit volume) and ε0 the permittivity of free space.It is one of the Maxwell’s equation.
What is the difference between the wave equation and differential equation?
The difference is in the third term, the integral over the source. In three dimensions, the wave equation, when written in elliptic cylindrical coordinates, may be solved by separation of variables, leading to the Mathieu differential equation .
