A cross section of Earth’s magnetic field can be represented as a vector field in which the center of Earth is located at the origin and the positive y-axis points in the direction of the magnetic north pole. The equation for this field is = where m is the magnetic moment of Earth....
Magnet is defined as a material that can produce its own magnetic field. There are three types of magnet: permanent magnet, temporary magnet, and electromagnet. Magnets are used in electric bells and generators.

The electro-magnetic force is greater than the combined spring force and the static and dynamic pressure forces of the medium. figure 1 DIRECT-ACTING 3-WAY VALVES Three-way valves have three port connections and two valve seats. One valve seal always remains open and the other closed in ...
Multi-terminal low-ESL devices use multiple physical terminals for each logical capacitor terminal and interleave them in such a way that the magnetic fields created by currents entering and leaving the device cancel to a large degree, resulting in lower inductance. Reverse Geometry ceramic capacitors...
This occurs as a result of the planet's gravity, and also because of the effects of its magnetic field. Now, if material from Saturn's rings is being lost and nothing new is added from time to time, the rings would be disappearing. ...
athe Concentrator must NEVER be used without the heat-resistant ceramic cloth shown in the illustration on the facing page,because the heat generated in the parts being worked on is sufficient to damage the magnetic ferrite material in the pole pieces. 因为在零件引起的热运作是充足损坏磁性纯铁材料...
