Sound-Responsive Magnetic Fluid Display
نویسندگان
چکیده
A new magnetic fluid device is developed in which the magnetic fluid is manipulated in sync with sound. The magnetic fluid moves due to changes in a magnetic field produced by several electromagnets installed above and below a shallow, horizontal acrylic panel in which the magnetic fluid is held. The voltage to each electromagnet is controlled according to sound input by computer processing, making the fluid pulsate like a living thing. In this paper, we propose the concept and design of the magnetic fluid display, and discuss the results of a demonstration of a trial wide-screen projection of the working device.

*Correspondence: Yasuhito Narita, Space Research Institute, Austrian Academy of Sciences, Schmiedlstr. 6, A-8042 Graz, Austria e-mail: [email protected] Magnetic reconnection in space plasmas remains a challenge in physics in that the phenomenon is associated with the breakdown of frozen-in magnetic field in a collisionless medium. Such a topology change can also be found in superfluid...

متن کاملDetermination of Sound Speed in a Magnetic Fluid Using Acoustomagnetic Effect
This paper describes the interferometric methodology for determining the speed of ultrasonic wave’s propagation in a magnetic fluid. The technique uses acoustomagnetic effect, which can be observed in a magnetized magnetic fluid, when elastic oscillations inside it. We describe the experimental setup and the measurement technique in detail. We determined the speed of ultrasonic waves propagatio...
