If there is no [magnet], where there is magnetism? Slowly progressive era, a magnet generations are the times. In medicine, the use of MRI to diagnose abnormal human tissue to determine disease square spigot magnet, this is what we are more familiar with the magnetic resonance imaging technology, the basic principles are as follows: positively charged nucleus, and spin motion. Typically, nuclear spin axis is arranged irregular, but placing a magnet, the spatial orientation of the nuclear spin transition from disorder to order when the applied magnetic field. MRI is characterized by the flow of the liquid does not produce a signal called flow effect or effects flow gaps. Therefore vascular tubular structure is gray circular punch magnet, and the blood is no signal black. This allows blood vessels and soft tissue can easily be separated. Normal cerebrospinal fluid surrounding the spinal cord surrounded by cerebrospinal fluid rare earth permanent magnet is black and white against the backdrop of the dura fat, spinal cord appear as a strong signal structure white. As for the ingredients that is iron, cobalt, nickel, etc. The special atomic structure, atomic itself has a magnetic moment. General chaos molecular arrangement of these minerals. Influence on each other nearly as magnetic magnetic zone .. but under external force (such as magnetic field) guide molecular orientation tends to show magnetic unanimously ... is commonly known as a magnet. FeCoNi is the most common sub-magnetic material is basically a magnet permanent magnet and soft magnetic iron permanent magnet is coupled with the spin of the magnetic material electronic angular momentum into a fixed direction is coupled with the current arrangement of soft (also a plus magnetic method) and other current will slowly lose remove soft iron magnetic NdFeB magnets, magnets, magnetic new Xin Tong from Dongguan City Tong Xin magnetic Limited offer.
