At a certain location in Africa, a compass 12^@ west of the geographic north. The northe tip of the magnetic needle of a dip circle in the plane of magnetic meridian points 60^@ above the horizontal . The horizontal component of the earth's field measured to be 0.16 G. Specify the direction and magnitude of the earth's field at the location. |

Answer» SOLUTION :`phi=12^@, theta=60^@,H_E=0.16G` `:.H_E=B_Ecostheta,"":.B_E=H_E/(COSTHETA)=(0.16)/(cos60^@)=(0.16)/(1//2)=0.32G` The TOTA magnetic field at the place is inclined at `12^@` TOWARDS west from GEOGRAPHIC north. |
