Ultrasonic Waves in Liquids Under Magnetic Fields-Underwater Magnetoultrasonics

Ultrasonic waves propagating in liquids under magnetic fields influence in velocity, amplitude and frequency. Generation of shear waves in water under magnetic field is also another characteristic phenomenon. From the analysis of velocity of SH-waves and expression of reflection coefficients from solid interface underlying water layer, substituting parametric values changes are observed in velocity and reflection coefficients. Relations between initial pressure and magnetic field in layered media are also discussed. Considering the earth's magnetic field spreading throughout all materials in the upper crust the present investigations may be useful in underwater magnetoultrasonics.
