A long, straight wire lies on a horizontal table in the xy-plane and carries a current of 1.40 µA in the positive x-direction along the x-axis. A proton is traveling in the negative x-direction at speed 2,60 x 10° m/s a distance d above the wire (i.e. z = d). (a) What is the direction of the magnetic field of the wire at the position of the proton? --Select-- v direction (b) What is the direction of the magnetic force acting on the proton? --Select--- v direction (c) Explain why the direction of the proton's motion doesn't change. This answer has not been graded yet.
