Two long parallel wires which are 0.03 m apart carry equal currents of 2.5 A. a) Calculate the net magnetic field at a point midway between the two wires if their currents flow in the same direction. Give magnitude and direction of Bnet. b) Calculate the net magnetic field at a point midway between the two wires if the currents flow in opposite direction. Give magnitude and direction of Bnet. c) Calculate the magnitude of the magnetic force per meter between the two wires. Explain when this force is attractive and when it is repulsive. d) What is the net magnetic force on a point charge q=0.5 C, located at 0.03m above the top wire in the figure and moving to the right with v = 30 m/s. Assume the currents are both to the right.

the d part cant be done without figure( eqution using in this part is F=qvBsin(angle), post the d part with figure if u really need answer for that )

and remaining question are done
