Magnetics question

2019 · 8 Apr · Shift 2 · Q49

JEE MainPhysicsMagneticsMCQ+4 / −1
Two very long, straight, and insulated wires are kept at 90° angle from each other in xy-plane as shown in the figure. These wires carry currents of equal magnitude I, whose directions are shown in the figure. The net magnetic field at point P will be : JEE Main 2019 (Online) 8th April Evening Slot Physics - Magnetic Effect of Current Question 165 English
