Theory: The magnetic force between two wires A and B is brought on by each wire producing a vector field at all points of the other wire. The unit of magnetic field is the telsa (T) and consider the differential length of the wire where the vector coincides with the wire and points in the direction of the current in the wire. Let r be the vector to the field point. The differential magnetic field produced is given by: u0/4*pi (Idl *r/r^2) where I is the current, r is the unit vector that poits to the wire element to the field, and u0 is the constant called the vacuum permeability constant. The magnetic field is proportional the the current I. dF= Idl * B giving the force F per unit length between two thin infinitely long parallel wires separated by distance D is F= 2u0/4*pi (IaIb/D) The force is attractive if the currents are in the same direction
