Stubborn stains in your plastic storage containers? A simple trick using a lemon can leave them fresh, clean, and good as new ...

BARCELONA — Computers are hungry beasts. They devour vast amounts of power, especially when writing data to memory—a process that traditionally uses electric currents and generates wasteful heat.

Using the finite element method (FEM) algorithm in combination with the database, the theoretical limit of remanence for MSR is analyzed. The demagnetization excitation optimization method and the ...

工件在磁粉探伤时将工件磁化；当工件的长轴与地磁方向一致并受到冲击或振动载荷时被地磁场磁化；工件磨削、电弧焊接、低频加热及强磁体接触被磁化等。只有在个别情况下工件上的剩磁有用处，但在绝大多数情况下，其上的剩磁都是有害的，故进行退磁 ...

Pulses of current through the coil will adjust the remanence of the AlNiCo magnet, thereby changing the flux and field in the air gap. A magnetic bias circuit with a compact volume of 0.27 cm 3 has ...
