10. A straight, stiff, horizontal 25-cm-long wire that has a mass equal to 50 g is connected to a source of emf by light, flexible leads. A magnetic field of 2.66 T is horizontal and perpendicular to the wire. (a) Find the current necessary to ""float"" the wire, that is, when it is released from rest it remains at rest. (b) What is the direction of the magnetic force? Sketch the 3 vectors (magnetic field, length, and magnetic force).

A straight, stiff, horizontal wire of length 25 cm and mass 80 g is connected to a source of emf by light, flexible leads. A magnetic field of 1.33 T is horizontal and perpendicular to the wire. Find the current necessary to float the wire, that is, find the current for which the magnetic force balances the weight of the wire. ___ A
