Magnetic field due to a current loopWe, I
magnetic field lines are directed from the South Pole to the North Pole. Thus, we can say that magnetic field lines form a closed curve. They can never intersect with each other.

Therefore, current high-resolution observational data support the results of this study by means of case analyses. These observations have also been explained theoretically7. The sun is magnetic, and its magnetic field elements can be classified into 5 groups according to their magnetic flux content...
Compression of a magnetic material leads to a change in its magnetic properties. We examine this effect using spin-lattice dynamics for the special case of bcc-Fe, using both single- and poly-crystalline Fe and a bicontinuous nanofoam structure. We find
The possibility that a field reversal would be an extinction event is very low. 场反转成为灭绝事件的可能性非常低。 There is very little historical evidence to show that previous reversals have caused extinctions. 很少有历史证据表明以前的逆转导致了物种灭绝。
Recent studies have found that the Earth'smagnetic field has weakened about 5% per decade. At its current rate, the next reversal could happen within the next century. 译文:最近的研究提供的证据表明,在过去50万年里有过5次磁逆现象。最近的一次发生在大约4.1万年前。最近的研究发现,地球磁场每十年减...

Current collection by an infinitely long, conducting cylinder in a magnetized plasma, taking into account the magnetic field of the collected current, is discussed. A region of closed magnetic surfaces disconnects the cylinder from infinity. Owing to this, the collected current depends on the ratio...
