Two long parallel wires each carry 2.7 Amp in the similar direction, with their centers 1.7 centimeter apart.
Part A Obtain the magnitude of the magnetic field halfway between the wires.
Part B Obtain the magnitude of the magnetic field at a point in the same plane as the wires, 1.7 cm from one wire and 3.4 cm from the other.
Part C Obtain the magnitude of the force of interaction (per length) between the wires.
Part D Tell whether the force is attractive or repulsive.
