A circular loop with radius R and mass M carries a current I and is lying on a rough but considerably flat table. A horizontal magnetic field of magnitude B is present on the surface of the table. Suppose the circular loop is rigid, and the surface of the table the xy plane
a) Draw a schematic diagram
b) Find the minimum magnitude of the magnetic field therefore that one edge of the loop will lift off the table?
c) Find what is the magnitude of the magnetic field if the loop has a radius 1 meter, mass of 3 kilogram and current on the loop is 10 Amp?
