If it is possible to calculate the earth's magnetic field at a given point (ranging between 0.25 to 0.65 Gauss), can an opposing field be created to lift an object? If the natural magnetic field is not strong enough, can it be amplified to the required level? My question is leading to whether a device could be created to amplify the natural magnetic field and a second device could be created to levitate above it carrying any given weight. The ground device would increase the amplification dependent upon the force requirements of the upper device's weight load. This leads to my second question, if the above is possible, would the ground device "feel" the full weight of the upper device? For example, if the ground amplification device weighs 10 lbs and the weight on the upper device is 100 lbs, would a person pushing the devices in unison require the force to push 10 lbs or 100? Thank you for your help in my hypothetical quest.
