A horizontal circular loop carries a current that looks anticlockwise then viewed from above. It is replaced by an equivalent magnetic dipole NS, which of the following is true?A. The line NS should be along a diameter of the loop.B. The line NS should be perpendicular to the plane of the loop.C. South pole should be below the loop.D. North pole should be below the loop. |

Answer» Correct Answer - B::C The magnetic field due to the horizontal circular loop is perpendicular to the plane of the loop and upwards. Therefore, the line NS of dipole should be perpendicular to the plane of the loop and north pole should be upwards or south pole should be downwards. |
