Passive buzzer have not internal drive circuit inside, We used to name them as acoustic. Passive work buzzer square wave signal. Passive buzzer can't make a sound by direct current.

EMAT probes have the following advantages:

1. No couplant is needed. Based on the transduction mechanism of EMAT, couplant is not required. This makes EMAT ideal for inspections at temperatures below the freezing point and above the evaporation point of liquid couplants. It also makes it convenient for situations where couplant handling would be impractical.

2. EMAT is a non-contact method. Although proximity is preferred, a physical contact between the transducer and the specimen under test is not required.

3. Dry Inspection. Since no couplant is needed, the EMAT inspection can be performed in a dry environment.

4. Less sensitive to surface condition. With contact-based piezoelectric transducers, the test surface has to be machined smoothly to ensure coupling. Using EMAT, the requirements to surface smoothness are less stringent; the only requirement is to remove loose scale and the like.

5. Easier for sensor deployment. Using piezoelectric transducer, the wave propagation angle in the test part is affected by Snell’s law. As a result, a small variation in sensor deployment may cause a significant change in the refracted angle.

6. Easier to generate SH-type waves. Using piezoelectric transducers, SH wave is difficult to couple to the test part. EMAT provide a convenient means of generating SH bulk wave and SH guided waves.
