Question

In the experiment with the two parallel wires (Figure 2), the scientist places the wires 1.0 cm apart and sends a current of 24 A through the wires. What will he observe?

A. The two wires will repel each other.

B. The two wires will attract each other.

C. The two wires will twist around each other.

D. Both wires will move upward slightly and no longer sag under their own weight.

E. The two wires will have no effect on each other.

in a second experiment,the scientist suspends a second wire parallel to the first wire as shown in Figure 2. When connected to the power supply, the two wires are in series and currents in the wires are in opposite directions. © 2016" Grand Canyon University. All Rights Reserved.

Explanation / Answer

When the current is opposite to each other in two parallel wires, the magnetic field produced by the passing current in each wire will be trying to push the wires apart by getting into the gap between the wires. It means that two parallel wires with current flowing in opposite direction through them will Repel each other.

EXTRA - Opposite is true for parallel wires with current flowing in same direction. The wires will attract each other .
