Upon the Direction in which the North Magnetic Pole has moved during the last two CenturiesIN an article upon Terrestrial Magnetism in the current number of thedoi:10.1038/007142c0X.Springer NatureNature
Once it stops wobbling, the north end should be pointing north. If you know roughly which direction is north (the sun rises in the East), you'll find your magnet's north pole. Floating magnet compass A great science project is to create a compass by floating a magnet on piece of ...
At what direction will a compass spin when at the North Pole? What are prevailing winds? What are some devices that indicate wind direction? What direction does heat flow? What direction is lateral? What does a wind vane measure? What direction does current flow?

aThe North Pole refers to the northern end of the earth’s axis, latitude 90ºN and longitude 0º, which is distinguished from the north magnetic pole. It was first reached by Robert E. Peary in 1909. 北极提到轴心、纬度90ºN和经度0º的北结尾,从北部磁极是卓越的。 它由罗伯特・ ...
Electric current flowing through a coil of wire produces a magnetic field, with the direction of current flow determining the polarity of the magnetic field When a voice coil is placed within the unchanging magnetic field of a permanent magnet, these two properties are realized. Switching the elec...
