A cooling fan electromagnetic dynamic principle
1, any one who has a magnetic material, so it will have two poles, we need think N pole and S pole and extreme intensity of magnetic field (strongest The strongest magnetic) Weak magnetic field strength in the middle.
2, the generation of electromagnetic: coil in the case of electricity produced by magnetic field, magnetic field direction is: the flow direction of the coil current 90 degrees counterclockwise as the magnetic N pole, is 90 degrees in the same direction as the S pole. Morning of dongguan macro electronic co. , LTD. , specializing in the production of cooling fans, have the professional automatic charger for rubber magnet magnetization.
3, the effect of magnetic field ( Same-sex repulsion opposites attract) In magnetic materials, N pole and S pole is relatively is namely in a magnetic material exists in the N pole and S pole, two magnetic materials for in-phase rejection, heteropolar attraction.
