Compact induction coils without a bulky permanent magnet are designed and operated as powerful electromagnetic acoustic transducers (EMAT) for contact-less ultrasound testing of metallic objects. More, novel and relevant applications for these EMATs are stimulated due to increased range of contact-less coupling, smaller sizes and less geometrical restrictions.

紧凑型感应线圈没有庞大的永久磁铁，被设计和操作为强大的电磁声学换能器(EMAT)，用于金属物体的非接触式超声波检测。由于非接触耦合范围更大、尺寸更小和几何限制更少，这些EMAT更多、更新颖和更相关的应用得到了刺激。
