A square loop of current is in a magnetic field. a. If the field is uniform, is there always a net force, never a net force, or sometimes a net force? Explain or prove your answer mathematically. If you said sometimes, explain under what circumstances you get a net force and under what circumstances you do not get a net force. b. If the field is NOT uniform, is there always a net force, never a net force, or sometimes a net force? Explain or prove your answer mathematically. If you said sometimes, explain under what circumstances you get a net force and under what circumstances you do not get a net force.

Consider a long, horizontal Large Wire with current of 10 A running through it. We want to levitate a horizontal, thin, 0.50 m length of wire above it. If the thin wire has a mass of 10 grams, and a current of 300 mA, how far above the Large Wire will it hover (net force of zero) due to magnetic and gravitational forces? A. If the thin wire hovers above the Large Wire due to their magnetic fields, are their currents going the same direction, or opposite directions. Explain. B. Draw a diagram and label the directions of currents, and all other relevant quantities and vectors. C. Find the distance above the Large Wire the small thin wire will hover (net force of zero). D. Would your answers to parts A and C change if we wanted to find a distance below (rather than above) the Large Wire that the smaller thin wire could hover, due to their magnetic fields. Explain. Don't calculate any values but draw a new diagram and explain how this situation compares to the problem above.
