Presume that there is a horizontal uniform magnetic field of 0.11 Tesla parallel to the ground. If a 0.787 mm diameter mosquito that was strangely made of copper wanted to float in midair by passing a current through its body that is perpendicular to the magnetic field, how much current would this take? (model that pesky mosquito as a cylindical wire, copper has a density of 8920 kg/m^3, you don't know how long the mosquito is)
