In a similar manner, one can show that wire #1 will experience a force due to the magnetic field of wire #2, and that this force will have a magnitude equal to that of F2 given in Eq.(1.11) but opposite
Magnetic Force Between Wires. The magnetic field of an infinitely long straight wire can be obtained by applying Ampere's law.
2. Two straight wires are in parallel and carry electric currents in opposite directions and with the same magnitude of 2.0 A. The distance between the two wires is 5.0 mm. One wire is infinitively long and the other wire is 0.30 m long. Is the magnetic force between the two wires repulsive or attractive?
To investigate the magnetic force between two parallel current-carrying wires and determine the magnetic permeability of free space, µo.
Forces between two current-carrying wires.
Magnetic Forces Balanced by Gravitational Forces
Free body diagram for one of the wires is a great idea. You are right that veritical component of tension should be equal to the force of gravity and horizontal component is equal to magnetic force between the wires. This gives you two equations with two unknowns.
In this case, your thumb points in the direction of the current, your fingers point in the direction of B. Your palm gives the direction of F. The force between two parallel wires. Parallel wires carrying currents will exert forces on each other. One wire sets up a magnetic field that influences the other...
Magnetic Force between Two Parallel Conductors. Bởi: OpenStaxCollege. 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 currents.
The force felt between two parallel conductive wires is used to define the ampere—the standard unit of current.
