The principle is used for the study of rotating, reciprocating, oscillating or vibrating objects. In others they are one or more rotating disks or a set of oscillating blades. These files attach to the head of a specific oscillating or rotating drill. This emission originates from high-velocity electrons oscillating within magnetic fields. Ultrasonic Contact Impedance (UCI) method determines hardness by measuring the frequency of an oscillating rod. Resonant transfer works by making a coil "ring" with an oscillating current. The oscillators in the transmitter and the receiver can never be oscillating at identical frequency. We can find the energy contribution for all oscillators oscillating at frequency formula 78. Ollin is pulsating, oscillating, and centering motion-change. Two common types are oscillating piston meters and nutating disk meters. The radio receiver connected to the receiving antenna detects this oscillating current and amplifies it. He described an electrochemical cell that produced an oscillating current. This occurs due to the spins of the individual atoms oscillating in tandem. The sound of raindrops hitting water is caused by bubbles of air oscillating underwater. It was fitted with an eight-round auto-loader system mounted in an oscillating turret.
