A magnetic field is the effect we can see from the movement of charges or the spin of electrons. The fields themselves can be static or changing. A field diagram can be used to show the interactions ...

At first glimpse, it may seem like infant stars and supermassive black holes have very little in common. Infant stars, or "protostars," haven't yet gathered enough mass to trigger the nuclear ...

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...

Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, ...

Abstract: Theoretical values of the magnetic field intensity outside a permanent magnet usually agree with experiment only at distance greater than the length of the magnet. This theoretical formula ...

If the magnetic field is parallel to the velocity ... carrying wire A wire carrying current is essentially a stream of charged particles moving in the same direction. It can be shown that the equation ...

Get Instant Summarized Text (Gist) Observations from the NSF VLA reveal a helical magnetic field in the HH 80-81 protostellar jet, similar to those in jets from supermassive black holes. This ...

Researchers at the University of Colorado Boulder (CU Boulder) have made a significant advance in magnetic field measurement. They have developed a new technique that uses atoms as highly precise ...

It was originally developed for CERN scientists. Rolex Magnetic fields are one of the most common factors negatively affecting the accuracy of a mechanical watch. Internal watch parts made of metal ...
