Consider a straight piece of copper wire of length 8 m and diameter 4.5 mm that carries a current I = 7 A. There is a magnetic field of magnitude B directed perpendicular to the wire, and the magnetic force on the wire is just strong enough to "levitate" the wire ( the magnetic force on the wire is equal to its weight). Find B. The density of copper is 9000 kg/m³ .
