It's just an electromagnetic field with polar repulsion....
edit; It's just like putting two magnets ontop of each other and making them float... Or using magnetic rings and putting them down a pole...
Also, the wires do not overheat because of the 'current/wire' ratio, but the resistance ratios of the power supply and the wires....

Commercial CRT Degaussers are available from parts distributors...
...and consist of a hundred or so turns of magnet wire
in a 6-12 inch coil. They include a line cord and momentary switch. You
flip on the switch, and bring the coil to within several inches of the
screen face. Then you slowly draw the center of the coil toward one edge
of the screen and trace the perimeter of the screen face. Then return to
the original position of the coil being flat against the center of the
screen. Next, slowly decrease the field to zero by backing straight up
across the room as you hold the coil. When you are farther than 5 feet
away you can release the line switch.

It looks really cool to do this while the CRT is powered. The kids will
love the color effects.
