How can i find the angle in this question
Dear student,
To find out the direction of magnetic field at three points, we have used Maxwell right hand thumb rule;
for example only due to wire having current 20 Amp, at point P, the magnetic filed is directed upward, and due to the wire having current 30 Amp , field at point P is downward. so the resultant magnetic field is the difference between these two separate fields.
Maxwell right thumb rule states that if your thumb shows the direction of current through a straight conductor, then the other fingers will encircle along magnetic file direction.
Answer:
BP= 2×10-5 T It will be perpendicular to the plane of the paper pointing upward or outward the paper.
BQ= 1×10-4 T It will be perpendicular to the plane of the paper pointing inward or downward.
BR= 4.7×10-5 T It will be perpendicular to the plane of the paper pointing upward.
Regards,
