The magnetic field is a vector field that represents the force per unit current on a test current. It is produced by current-carrying conductors and is described by the Biot-Savart law. The magnetic field is a solenoidal field, meaning that it can be expressed as the curl of a vector potential.
The electric potential, also known as the voltage, is a scalar function that describes the potential energy per unit charge at a given point in space. It is related to the electric field by:
∇×B = μ₀J
Gauss's law states that the total electric flux through a closed surface is proportional to the charge enclosed within that surface. Mathematically, it is expressed as:
E = -∇V
∇×E = -∂B/∂t
∇⋅E = ρ/ε₀
