From a top view perspective and with the current polarity reversed, in what direction does the north pole of the compasss needle point to when the compass was positioned around the vertical current cwrrying straight conductor?
Answers
Answer:
The north pole of the compass needle point to the direction tangent to the circle
Explanation:
The north pole of the compass needle point to the direction tangent to the circle when the compass was positioned around the vertical current carrying straight conductor.
Hans Oersted proposed the relationship between magnetism and electricity. He said that when there is electricity flows in a wire, a magnetic field is created around the wire.
This is manifested in this situation when we positioned the compass around the vertical current carrying wire, the north pole of the compass aligns to the north pole of the earth. If you will observe it, you can notice that all the compass are all pointing in one direction.
However, when a current flows into the wire, you can observe that the direction of the north pole of the compass is tangent to a circle. In a simple term, you can see that if you were to connect the north pole of the compass, you can find out that they form a circle. This is because the magnetic field of the current is circular due to the wire being circular in form
