Let’s investigate analogous magnetic situations involving long straight wires. EXPLORATION 19.7 – The magnetic force between two parallel wires A long straight wire (wire 1) carries a current of I1 into the page.
Figure below shows two long parallel wires separated by distance d and carrying currents I1 and I2.
The force felt between the wires is used to define the the standard unit of current, know as an amphere.
Force Between Two Parallel Wires.
Magnetic Force Between Wires. The magnetic field of an infinitely long straight wire can be obtained by applying Ampere's law.
To investigate the magnetic force between two parallel current-carrying wires and determine the magnetic permeability of free space, µo.
You might expect that there are significant forces between current-carrying wires, since ordinary currents produce significant magnetic fields and these fields exert significant forces on ordinary
