Two wires are oriented perpendicular to each other as shown in the figure. Wire 1 carries a current of 7.5 A upward, and Wire 2 carries a current of 1.5 A to the right. What is the magnitude and direction of the net magnetic field at point P, if r1 = r2 = 30 cm?
Solution:
---> Let the net magnetic field is B.
---> Cross (×) in a small circle shows the direction inside the screen/paper.
---> We find the direction of magnetic field by right hand thumb rule.
