Two identical magnets are placed perpendicular to each other with their unlike poles in contact. If each magnet has a magnetic moment 'M', what is the magnetic moment of the combination? |

Answer» Solution :Magnetic moment is a vector It acts along South to NORTH . The RESULTANT of two perpendicular vectors is obtained by USING parallelogram law of vectors . Here `M_1 = M_2 = M ` `:.` New magnetic moment ` = sqrt( M^(2) + M^(2) + 2M. M cos THETA ) = sqrt( M^(2) + M^(2) + 0)` New magnetic moment = ` sqrt(2) M` |
