a) Draw the lines of magnetic field B produced by the wire.
b) Calculate the magnetic field B produced by the wire at a distance 6 cm from the wire (at point P as shown in the picture).
c) A proton travels in direction vp (vp = 6x105 m/s). The proton is a distance of 2 m from the wire. What is the force experiened by the proton by the magnetic field? Include a magnitude and direction.
