The Effect of Frequency of Electromagnetic Vibrations on

The amplitudes of the electromagnetic vibrations at 5 kHz were calculated to be on the order of micrometers but those at higher frequencies were on the order of nanometers. It was found that the nanometer-sized amplitudes resulted in the disappearance of the increased cooling rate caused by electromagnetic vibrations observed at lower frequencies.
