From the post "Wait A Magnetic Moment" and the correction made in "Erratum, 2D Flat and Flatulent",
The magnetic moment of an electron in orbit,
\(S_e=\sqrt{2}qc r_{es}\)
If \(r_e\) has a time component,
\(r_e=r_{eo}e^{i\omega t}\)
then
\(S_e=\sqrt{2}qc.r_{eo}e^{i\omega t} \)
and \(S_e\) will resonate as \(r_e\) at,
\(\omega^2_o= \cfrac { d\, r_{ e } }{ d\, T } \cfrac{\partial}{\partial\,r_e}\left(\cfrac { d^{ 2 }T }{ dt^{ 2 } }\right) \)
From the post "Gravity Wave and Schumann Resonance", Earth has a gravity wave at 7.489 Hz and Schumann resonances at 7.83 Hz.
If, assuming no damping,
\(\cfrac { d\, r_{ e } }{ d\, T } \cfrac{\partial}{\partial\,r_e}\left(\cfrac { d^{ 2 }T }{ dt^{ 2 } }\right)=7.83^2\)
is applied to a magnetic material where the electron moment is aligned into magnetic domains, we might just have a levitating magnet or lodestone.
\(\cfrac { d^{ 2 }T }{ dt^{ 2 } }\) is probably provided by a heat source or indirectly by a electric charge.
\(\cfrac { d\, r_{ e } }{ d\, T }\) is characteristic of the material dependent on temperature.
At the right combination of a heat source and temperature, the material will levitate.
If a electrical voltage is to provide for \(\cfrac { d^{ 2 }T }{ dt^{ 2 } }\) then from the post "Rectified Waveform To The Rescue",
\(\left|\cfrac { d^{ 2 }T }{ dt^{ 2 } }\right|=\omega_dT_o\)
where \(T_o=V_oI_ocos(\theta)\), \(cos(\theta)\) is the power factor, and \(V(t)=V_oe^{i\omega_d t}\).
It is unknown how the material will behave, however we can replace,
\(\cfrac{\partial}{\partial\,r_e}\left(\cfrac { d^{ 2 }T }{ dt^{ 2 } }\right)\)
with
\(\omega_dT_o M_{t2}=\cfrac{\partial}{\partial\,r_e}\left(\cfrac { d^{ 2 }T }{ dt^{ 2 } }\right)\);
that is factor \(\omega_dT_o\) can be distilled. \(M_{t2}\) can be considered a material characteristic.
We have
\(\left|\cfrac { d\, r_{ e } }{ d\, T }\right|\omega_dT_oM_{t2} =7.83^2\) or
\(\omega_d=7.83^2.\cfrac{1}{\left|\cfrac { d\, r_{ e } }{ d\, T }\right|M_{t2}V_oI_ocos(\theta)}\)
instead.
At a suitable cold temperature, adjust \(\omega_d\) as per above expression until the magnet/lodestone levitate. Make sure that the material is correctly orientated, that the magnetic domains, North pole, is downward.
