1. An apparatus comprising:
one or more portions of material configured to vibrate at one or more ultrasonic frequencies when the material is positioned within a varying magnetic field, the one or more portions of material having shapes that correspond to a frequency of the varying magnetic field applied to the apparatus from an external source;
wherein a resonant mode of the one or more portions of material corresponds to the one or more ultrasonic frequencies; and
wherein the one or more portions of material configured to vibrate at the one or more frequencies are positioned so that, when the varying magnetic field is applied to the apparatus, the vibration caused by the varying magnetic field provides increased cooling within a cooling system.
