Teaching Haryana (HPSC) Assistant Professor Mock Test 2025 Physics Moving Charges and Magnetism Magnetic Field
Three infinitely long thin conductors are joined at the origin of coordinates and lie along the x, y and z-axes. A current i flowing along the conductor lying along the x-axis divides equally into the other two at the origin. The magnetic field at the point (0, –a, 0) has magnitude
