变化的磁场 meaning in English
varying magnetic field
Examples
- The fluctuating mangnetic field cutting across the turns or loops of wire of the secondary coil sets up an electrical pressure or voltage in these loops .
起伏变化的磁场横向切割着次极线圈的线匝和线环时，会在这些线环中引起电压。 - The fluctuating magnetic field cutting across the turns of loops of wire of the secondary coil sets up an electrical pressure or voltage in these loops .
起伏变化的磁场横向切割着的次级线圈的线匝或线环时，会在这些线环中引起电压。 - But electric fields also curl around magnetic fields that are changing with time , and magnetic fields curl around electric fields that are changing with time , never mind any charges or currents
但在随时间变化的磁场周围也会产生电场，在随时间变化的电场周围也会产生磁场，而不需要任何电荷或电流的介入。 - Insulation shell in a new induction shaft coupling is a main element to solve leakiness of magnet pump , it often works in changing magnetic field so that eddy current is produced , and eddy current results in wastage and decreasing the efficiency
摘要磁力联轴器中内外转子间的隔离套是磁力泵实现无泄漏的主要零件，由于磁力联轴器工作时，隔离套便处在变化的磁场中，则其内部将产生涡流，导致涡流损耗和传递效率降低。 - According to more effect , when the hore component is placed in a gradient field , at the same time the direction of the current is perpendicular to the direction of the voltage , then between the two parallel side face come out the hore voltage . when hore component is set in this kind of uni - gradient magnetic field and the electric current is unchanged , the voltage output of hore component will be proportional to the position of the hore component in the magnetic field . so we can use the hore component to measure the movement of hore component against magnetic field
根据霍尔效应可知，置于磁场中的霍尔元件若电流方向与磁场方向垂直，则在霍尔元件垂直于磁场和电流方向的两个侧面将产生电势，将霍尔元件置于强度随空间位置线性变化的磁场中，且控制电流恒定，输出就正比于霍尔元件处于磁场中的位置，因此可以用霍尔元件来测量磁场与霍尔元件间的相对位移量。
