您要查找的是不是：
- Sunspots, the Solar Cycle, and solar prominences are all caused by the Sun's changing magnetic field. 黑子，太阳活动周期，以及日珥都是由太阳不断变化的磁场造成的。
- If the charge is moving, a magnetic field is also produced.A changing magnetic field also produces an electric field. 运动电荷则同时产生磁场，磁场的变化也能产生电场。
- The magnetic stimulation is the process that the excitable human tissue is acted with the electric field induced by the changing magnetic fields. 摘要磁刺激是利用变化磁场产生的感应电场作用于可兴奋人体组织的过程。
- When a TMS coil is activated near the scalp, an extremely powerful and rapidly changing magnetic field travels unimpeded through skin and bone. 当TMS的线圈在头壳附近启动时，某个极为强大且快速变化的磁场就轻易穿越皮肤及头骨。
- Trans-cranial magnetic stimulation (TMS) is the process that excitable human brain tissue is activated with the electric field induced from a changing magnetic field. 经颅磁刺激是利用变化磁场产生的感应电场作用于可兴奋人体脑组织的过程,磁聚焦性能是经颅磁刺激线圈设计的一项重要指标。
- 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。
- MRF (magneticcurrent recharge fluid) damper changes magnetic field via coil current to adjust flow of magnetic current recharge fluid in damp channels, control of damp fore of damper is realized. 磁流变液减振器通过线圈电流改变磁场调节磁流变液在阻尼通道中的流动，实现对减振器阻尼力的控制。
