Is the magnetic force between the two wires repulsive or attractive?
If the wires are perpendicular however, the force between them is 0.
The equation to calculate the strength of the magnetic field around a current-carrying wire is: B perpendicular = µoI / (2πr).
To investigate the magnetic force between two parallel current-carrying wires and determine the magnetic permeability of free space, µo.
Magnetic Force between Two Parallel Conductors. This field is uniform along wire 2 and perpendicular to it, and so the force F2 it exerts on wire 2 is given by F = IlB sin θ with sin θ = 1
When a wire carries a current that is perpendicular to a magnetic field, there is a force on the wire perpendicular to the current and field.

Magnetic Forces Cannot Perform Work on Moving Charges. Force is always perpendicular to velocity, therefore the
3 Magnetic forces on a moving charged particle 3.1 The magnetic force on an electron in a wire 3.2 The magnetic force on a moving charged particle 3.3 Motion of a charge along or perpendicular to
The magnetic force is perpendicular to the velocity, and so velocity changes in direction but not magnitude. Uniform circular motion results.
