Vortex vs. Hydra
Attach the vortex to the magnet and lift it a bit off the ground, get in and fly.
It will of course work with any magnetic vehicle, but the Vortex is the only vehicle that can propel itself through the air.
Aircraft aren't magnetic and neither are boats, - with one exception
Dinghy on a string
Bikes (except Quads) are magnetic but only without a rider, mounting a bike attached to a magnet will instantly detach it.
Bicycles aren't magnetic.
The Quarry and export crane are the only cranes with working magnets, - the magnet on the crane in LV doesn't work.
Another option is the Up, Up and Away Leviathan:
Some a**hole stole my lawnmower
Apart from Securicar's the Leviathan can lift vehicles weighing 1500 kg. max (lifting a 1500 kg. vehicle will require some patience)
Although it's only available during a mission (w/o mods etc.), there's no time limit or movement restrictions during the mission.
And since it's a mission objective it won't disappear if left somewhere.
Unfortunately you can't do exports during the mission:
You can however use it to rearrange garage content:
Dinghy in garage
The rope hasn't got collision, so it passes effortlessly through objects.
Another useful storage location for a Dinghy
But until global warming sets in in earnest the usefulness is pretty limited
Dinghy in pool
Two magnets doesn't attract, but you can attach the same vehicle to different magnets
It's my bike I tell yeah, MINE!
You can't lift or tow the Leviathan by it's magnet

Strange things may happen if you're fooling around in an attached vehicle and everything suddenly come tumbling down

The Leviathan magnet can be released at anytime by pressing the fire button, CJ doesn't have to be in the helicopter.
Notes on boats: The boats are "anchored" when their engines are off, they'll fiercely resist horizontal movement but can still be lifted up or down.
To release the "anchor" get in and turn the engine on.
The Leviathan floats, so it can be landed on the water.
Always remember to carry a "rubber" when you're out having fun
Here's a small cleo script that puts the magnet on the Leviathan unlocked by "Up, Up and Away" after the mission is completed:
It was used for some of the above screenshots
A cheatdevice can probably do the same for PS2 users
And sorry about hitting the wrong button before finishing the post
