I Magnetic dipole in vacuum near absolute zero

Click For Summary
A single atom in a vacuum at near absolute zero is expected to retain its magnetic dipole due to its intrinsic properties. The magnetic moment is determined by the atom's ground state and its total spin. Atoms with half-integer total spin will definitely exhibit a magnetic moment, even in the absence of external fields or interactions. There is curiosity about whether this phenomenon has been experimentally verified. Overall, the existence of a magnetic dipole in such conditions is supported by theoretical understanding.

TL;DR
Will the magnetic dipole of a single atom in vacuum at near zero kelvin still exist?
Consider a single atom (or particle) in a vacuum (without electric, magnetic or gravitational field) at near zero kelvin (i.e., no photons or particles striking it). I am curious if it will still have a magnetic dipole? If there still is (which I believe), had this been shown experimentally?

Why would you think that the atom's magnetic moment will not exist near zero Kelvin? The atom will have the magnetic moment of its ground state. If it has a half-integer total spin, it will most certainly have a magnetic moment.

Thread 'Why higher speeds need more power if backward force is the same?'

Power = Force v Speed Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W Force/tension in rope stay the same if horse run at 0.73m/s or at 15m/s, so why then horse need to be more powerfull to pull at higher speed even if backward force at him(rope tension) stay the same? I understand that if I increase weight, it is hrader for horse to pull at higher speed because now is backward force increased, but don't understand why is harder to pull at higher speed if weight(backward force)...
