An infinitely long conductor PQR is bent to form a right angle as shown. A current I flows through PQR. The magnetic field due to this current at the point M is H₁. Now another infinitely long straight conductor QS is connected at Q so that the current is I/2 in QR as well as in QS, the current in PQ remaining unchanged. The magnetic field at M is now H₂. The ratio H₁/H₂ is given by

Question

Infinity Learn · Accepted Answer

Magnetic field at any point lying on the current carrying straight conductor is zero.Here $$H1$$ $$=$$ Magnetic field at M due to current in PQ.        $$H2$$ $$=$$ Magnetic field at M due to QR                $$+$$ magnetic field at M due to QS                $$+$$ magnetic field at M due to PQ
