1. Although the voltage of the magnetizer determines the strength of the magnetic induction pressure, it is also related to the capacity of the capacitor of the magnetizer. For example, the voltage of a magnetizer is 2000V, 4000UF, which cannot be saturated with a certain magnet. Maybe it can be fully charged with 2000V 5000UF. From this point of view, the magnitude of the magnetizer's voltage cannot determine its magnetic induction intensity, so Morty uses a formula to calculate the magnetic induction intensity through the magnitude of the voltage.
2. Through the principle of electromagnetic induction, we know that changing magnetic field can produce electric current, and changing electric current can also produce magnetic field. The principle of magnetizer is made by the principle of electric current alternating magnetic field. And what determines the magnitude of the current? It is not only determined by the power of the magnetizer, but also by the wire package of the magnetizer. The number of coils in the wire package determines the size of the current, that is, the size of the magnetic field. In addition, the size of the center hole of the wire package also determines the density of the magnetic lines of force. Generally speaking, the smaller the center hole, the denser the magnetic lines of force (but, if it is too small, the magnetic steel cannot be put down). Therefore, the intensity of magnetic induction is also related to the wire package, so the magnetic induction intensity cannot be estimated by voltage. Although the larger the magnet, the greater the required magnetic induction intensity to make it saturated, but the required magnetic field intensity is not completely proportional to the size of the magnet. Therefore, under the influence of many factors, there is no formula at all for the magnetic voltage and magnetic induction intensity you mentioned. Even if there is, it is useless to know this T because you still cannot calculate the relationship.
