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?
The force is repulsive when the currents are in opposite directions. The magnetic force per unit length (F/L) between two parallel long wires carrying currents, I1, I2 and separated by a perpendicular distance, d, is given by
Figure 1.9: Force between two long straight parallel wires. Wire #2 will experience a magnetic field of Eq.(1.6) due to wire #1 given by.
Thus we see that flux lines which travel in the same direction, as in the space between the wires' pro-duce repulsion. From the foregoing we see that such
Magnetic Force between Two Parallel Conductors. Bởi: OpenStaxCollege. You might expect that there are significant forces between current-carrying wires, since
First let’s look at some simple electrical experiments involving the magnetic force between current carrying wires
As the natural forces applied between two magnets can either be attractive or repulsive that is the direction of magnetic force can be either way and hence it is considered as a vector quantity.
1. To investigate the magnetic force between two current carrying wires.
Therefore the magnetic field produced by the long straight wire will be greater at the top of the loop than it is at the bottom of the loop. Furthermore, recall that the force between two current carrying wires is attractive when the wires carry current in the same direction, and repulsive when the wires...
