2Nd, thorough analysis: The Earth may say is an extremely marvelous thermonuclear reactor, when the earth interior pressure achieved certain critical, in the Earth material may decay the nuclear matter is called as the thermonuclear material, can have the thermonuclear reaction, thus has the huge energy, then the melted partial materials, form the rock magma are the liquid state materials, this response stratification plane is possibly many stratification planes, first possibly is located between the earth's crust and the mantle, upward next two transfers, displays for the light density material diastrophism as well as density upper mantle material phenomena and so on solidification; Under second possibly is located between the mantle and the core, the pressure is more formidable, causes not not easily to have the thermonuclear reaction thermonuclear material to have the response, forms the relative quite stable liquefied material level, simultaneously is upward next two transfers, forms the counter-flow phenomenon which the high density under mantle as well as the high density core material contact liquefies and is far away cools; These material periodicity regular movements and so on convection as well as Earth polar axis rotation are possibly the basic source powers which the terrestrial magnetic field produces.

深入剖析：地球可以说是一个非常奇妙的热核反应堆，当地球内部的压力达到一定的临界，地球物质中可衰变的核物质统称为热核物质，就会发生热核反应，从而产生巨大的能量，进而融化部分物质，形成岩浆即液态物质，这个反应层面可能是多个层面，第一层可能位于地壳与地幔之间，向上下两边对流，表现为轻密度物质的地壳运动以及中密度上地幔物质的固化等现象；第二层可能位于下地幔与地核之间，压力更为强大，引起不易发生热核反应的热核物质发生反应，形成相对比较稳定的液化物质层，同时向上下两边对流，形成中高密度的下地幔以及高密度地核物质的接触液化和远离冷却的对流现象；这些对流以及地球极轴自转等物质周期性规律性运动可能是地球磁场产生的根本源动力。
