Summary
[edit]
| Description |
Definition of magnetic energy of permanent magnet. The magnetic energy (red curve) is a product of flux density B and magnetic field strength H. It is calculated for the second quadrant, through which the demagnetising curve (blue colour) is plotted. The magnetic energy takes a maximum (BH)max, at which there is optimum working point (Ba, Ha) of a magnet. Br is the remanence, and BHC is the coercive force. Definicja energii magnetycznej magnesu. Energia magnetyczna (czerwona krzywa) jest obliczana jako iloczyn indukcji magnetycznej B i natężenia pola magnetycznego H dla krzywej odmagnesowania znajdującej się w drugiej ćwiartce wykresu (niebieska krzywa). Wartość energii magnetycznej przyjmuje maksimum, dla którego znajduje się optymalny punkt pracy magnesu (Ba, Ha). Br oznacza remanencję, a BHC koercję. |
