You could build a Tesla Coil and utilize the strong electric field but your probably talking about resonant magnetic induction. Consider the royer oscillator. I have been unsuccessful with it so far but it works. The colpitts oscillator works well too but don't expect a lot of power.

A: A variable power supply has no disadvantage since it can replace a fix power supply. The disadvantage will rest with the additional cost to make one.
How do you build a wireless circuit?
I don't believe what you are saying is possible in full. The closet i have ever come to a "wireless" circuit is having a power supply run a fan on a motor that would then blow wind against another fan that was attached to a generator, which then fed into a light bulb and finally back to the power supply. The energy did not travel through a wire, but instead by air. But it is unlikely that there is a 100% wireless circuit.
What is the best choice for a replacement power supply for power supply ratings?

What is an internal wireless device?
That is a device that is inside the computer. An internal hard drive, for instance, is physically mounted inside the computer. It is not made to be used outside the computer, though there are kits to convert internal hard drives into external drives. There are external storage devices that are made to plug into a USB port. External devices either require their own power supply, or they get power from a USB socket. Internal devices get their power from the power supply which is already in the computer.

Can you use a power supply with more amps and not fry the unit?
you will need to be allot more specific on what you are trying to do here. what is the difference in amps. what is the device Generally speaking it is good practice to only use the power supply that the device is rated for. the biggest issue you will have is this Power = voltage * current (simple version) if the power supply you had was 12v at 1 amps then you ca supply 12Watts of power if the power supply you had was 12v at 10 amps then you can supply 120Watts of power Just because you can supply 10 amps, and all you need is one, means your power supply is bigger than it needs to be. The device will draw what it is intended to draw. Just make sure the voltage matches.
