Book Free DemoLet us do the following activity to understand the magnetic effects of an electric circuit.
Steps:
- Take a straight, thick copper wire and fix it between the point X and Y in an electric circuit, as shown in the below figure.
Electric circuit
- The wire XY is maintained perpendicular to the plane of the paper.
- Horizontally, place a small compass near this copper wire.
- Observe the position of its needle.
- Pass the current through the electric circuit inserting the key into the plug.
- Observe the change in the position of the compass needle.
We observe that the needle is .
What does it mean?
It means that the electric current flows through the copper wire have .
Thus, we can state that .
