Like a pool noodle or torus you put on an axle that causes less vibration, this could cause greater lifespan and reduced maintenace and at durable machinery like excavators, elevators, trucks, agricultural machinery, HVAC fans (quieter), and even piston rods, electric generators, fair amusement rides, mining equipment, petroleum sector equipment like pumps, robots, manufacturing robots and machines, human companion robots, pumps, at if just possibly 2 times to an order or magnitude less eccentric wear, quieter operation, and greater intervals between maintenance is beneficial then a hundredth of of the system energy used at magnetic damping of vibration could be of value. Software that automatically generates magnetic damper forms, 3D printed forms or parts, or also pick and place robots could make magnetic dampers based on auto generating of damper shape, field, vibration measurements or models, and energy utilization specifications, the software could recommend 3D printed dampers and their field receptor affixables (like damping an axle the field receptor affixable might be a split side length of pool noodle). Some ferromagnetic objects being magnetically damped could omit the affixables), magnetic dampers and affixibles could be new engineering,
One way of doing magnetic damping without wiring is to have a 3D printed or other manufacturing technique where the magnetic damper part has an integral RF antenna similar to wireless phone charging, this might be RFID tag sized or less, and a RF frequency that only travels a short distance in space before being absorbed by anything, even cloth and polymers is utilized, possibly THz RF could transmit the energy the antenna turns to electricity but anything, even polymers, around it would absorb the Thz energy so the outside of the machine was RF neutral and noninterfering, the amount of magnetic damping. Engineers and software could figure out if periodic nudge magnetic damping, or continuous magnetic damping was simultaneously more function supporting, lifespan increasing and decreasing of the interval of maintenance, at HVAC fan or other systems with frequent starts there could be a moment (nudge) of lots of dampening to omit jolting, then there is the thing where energy is only used at the magnetic damper when the machine is at higher variability, or a higher precision preferred state are valued like a crane with a swaying load at the place and position part of the activity of moving something with a crane, or agricultural machinery driving over terrain and uneven terrain vibrations and flexion benefitting from magnetic damping, sometimes I perceive I have heard an oscillating him from machines, perhaps, to my perception this has taken a few seconds to build up, if some oscillating hums are associated with non optimal machine durability (beat frequencies that move components, eccentric wear) then it is possible just a nudge of magnetic damping could change the oscillation state of the machine to the greatest longevity version. Then besides magnetic damping nudges there is continuous magnetic damping, that,

Putting eentsy weights on axles changes their vibration characteristics and can reduce eccentricity of motion, to touchlessly do the same thing at a variety of places at a machine, putting a couple grams of gallium on an axle then melting it and pooling it up with a laser to minimize vibration and eccentricity is possible, also the laser editing of the gallium's position could be interactive, sensing vibration or eccentricity, the laset moving some gallium, sensing again, and optimizing to produce minimal vibration and eccentricity, Gallium Bismuth mixtures could be laser friendly but omit melting at an engine
