A long straight wire carries a current of around 61.8 A. the electron, traveling at 6.63 × 107 m/s, is 5.42 cm from the wire. Determine the magnitude of the magnetic force on the electron when the electron velocity is directed (i) to the wire, (ii) parallel to the wire in the direction of the current, and (iii) perpendicular to the two directions stated by (i) and (ii)?
