Why is there permanent magnetism? Does that means perpetual mobile?
According to the Maxwell equations, maintaining a static magnetic field needs not additional energy supply into the system. The energy trans...
Why does sintered Nd-Fe-B provide higher magnetic field when device size is limited to several centimeters?
2.Magnetic moment can be measured (with) by using the Helmboltz coil. Take a sintered Nd-Fe-B of 10×10×10 mm (SANMAG-N48M) for example, its ...
