Use the antimatter as a power source- makes more sense, if you can build and shield the reactor in a small enough and light enough package, using electric motors to power lift fans is possible. Ion engines?, perhaps if you are referring to spaceships. In the same sence, using local magnetic fields to levitate just above Earth's surface is probably impossibe. If you are referring tho space ships, then having some means to empower large powerful electrical and/ or magnetic fields could be used to push against Earth's or the Sun's fields. There is mention of using such an effect, it is similar to solar sails, except it suffers less as you move away from the Sun. The scheme I have seen is using magnetic fields to contain an extended cloud of charged particles. These will interact with the Solar wind to produce thrust. The major problem is that these charged particles need to be replenished as the magnetic confinement is not 100% efficient. At some point the tanks of material could be better used in an ion engine.
[EDIT] I should say that maglev using opposition to Earth's magnetic field is probably impossible, it is just too weak. Using strong magnets to repell each other is a different matter (like maglev trains).

How can antimatter have a repulsive force on other masses, when it has positive mass but opposing charge?

In theory, an antimatter atom should even be neutral so it should have no different interaction with the outside world as any regular hydrogen atom.
Because we can.
