... magnetic field is roughly the same shape as the field of a bar magnet. However, the earth's magnetic field is inclined at about 11º from the axis of rotation of the earth, so this means that the earth's magnetic pole doesn't correspond to the Geographic North Pole and because the earth's core is mol ...

Lecture 5
... J/sec. The power expended in a given circuit can be calculated from the equation P = E × I or P = I 2 × R. Power may also be expended in doing mechanical work, in producing electromagnetic radiation such as light or radio waves, and in chemical decomposition. The movement of a compass needle near a ...
