It's not stupid at all, it's actually quite clever!
The only issue is that many fans already magnetic fields to spin. The one in your computer very likely does!
Maybe discuss things more conceptually than specifically? Just because the idea is already in use doesn't mean your concepts are.. It just means someone else got there first.

The basic rule of physics with magnetic fields is that any point in space can only have a magnetic field in one direction and strength. Then there's the one over distance cubed field strength rule. There's also a dissipation rate for when the original source disappears.
For me, the only way for aeronautical levitation using magnetic fields would be a high-frequency alternating field, so that a vehicle could create a magnetic field around itself, rapidly switch polarity and them push itself against that magnetic field.
Maglev trains use the magnetic fields themselves to accelerate and decelerate the train.

My original idea was to use magnets in conjunction with fans underneath the vehicle with additional fans to push and/or slow down, or stop the vehicle
There are two particularly notable types of maglev technology:
For electromagnetic suspension (EMS), electronically controlled electromagnets in the train attract it to a magnetically conductive (usually steel) track.
Electrodynamic suspension (EDS) uses superconducting electromagnets or strong permanent magnets which create a magnetic field that induces currents in nearby metallic conductors when there is relative movement which pushes and pulls the train towards the designed levitation position on the guide way.

Magnetic lines of force cannot cross each other......
A magnetic field to counter earths natural one and supply "lift" ie anti gravitic action can be calculated by somebody with a better grasp of the math.....
All that need be done is to provide the opposite pole in the vehicle to repel it from earth.....
the rest is switching by computer to control the result.....providing sufficient power to do so .....priceless.....
