A long straight wire suspended in the air carries a conventional current of 8.6 amperes in the -x direction as shown (the wire runs along the x-axis). At a particular instant an electron at location < 0, -0.003, 0 > m has velocity < -1.5 ? 105, -1.8 ? 105, 0 > m/s.

a) What is the magnetic field due to the wire at the location of the electron?
=
b) What is the magnetic force on the electron due to the current in the wire?
=
(c) If the moving particle were a proton instead of an electron, what would the magnetic force on the proton be?
=
