YES IT IS POSSIBLE - e.g. a 1T earth magnet can lift 6.3kg 5cm -
6 lbs levitation for a small magnet. That's 6 lbs over the 1 cm^2 area of the magnet. Add more magnets and more area, and you lift more weight.
With an area 1000 cm^2 there's 1,000 magnets underneath. 1000 x 6 lbs = 6,000 lbs = 3 tons...
1 T is about the limit. Many scientists are working hard to make stronger, lighter, bigger magnets for motors and generators.
calculate the force from here:
https://en.wikipedia.org/wiki/Force_between_magnets , see the section on force between two cylindrical magnets --- in this example of cylindrical magnets the magnetization (mu_0 M) = 1 tesla, so M = 1 tesla / mu_0 = 7.96 x 10^5 A/m because mu_0 = 4 pi x 10^-7 N/A^2.
one magnet with north pole facing up, other magnet above it with north pole facing down.
the density of permanent magnets is approximately 10,000 kg/m^3, the mass of each magnet is about 7.85 x 10^-3 kg = 7.85 grams.
use the wikipedia equation to solve for the levitation height x if you make the levitating force equal to the gravitational force = 7.85 x 10^-3 kg x 9.8 m/s^2 = 7.7 x 10^-2 newtons. I get about 5 cm for levitation height by using the point dipole approximation (which does not account for tipping - you'd have to do the levitation in a tube). I also get about 62 N for the force needed to push the levitating magnet down to the magnet on the table, i.e. the maximum load that can be suspended is about 6.3 kg.
Now, if you use a 1 cm diameter, 1 cm tall superconductor for one of the magnets, and it becomes perfectly diamagnetic under the action of the other permanent magnet, you will get the same answer as for two permanent magnets above. This is because the superconductor responds to the permanent magnet by flowing current to oppose the permanent magnet's field, see
https://simple.wikipedia.org/wiki/Lenz's_law . Perfect diamagnetism means 100% of the field is opposed, i.e. exactly like the two permanent magnets. But the currents only flow to the maximum level induced by the permanent magnet
Force depends on the flux density of the magnets.
The levitating pressure (force per unit area) scales as the square of the flux density and inversely with the levitation height.
Stronger magnets, more force. Heavier object, less height.
you can make a fast pulse with fat wire but the field will be low, or you can make an intense pulse with thin wire but it will take some time to reach maximum.
