Module 5.1: Linear Currents

	Q1.  In configuration (a), current I1 is along the -z-axis and current I2 is along the +z-axis. What is the direction of the force acting on I1?       Force acting on I1 is zero.       Force acting on I1 is along the +y-axis.       Force acting on I1 is along the -y-axis.
	Q2.  In configuration (b), I2 surrounds the z-axis and flows in the positive z-direction, and and I1 lies in the x-y-plane and is parallel to the x-axis, as shown. Both currents are infinitely long. What is the direction of the magnetic force acting on the part of I1 to the right of the y-axis?       Force is zero.       Force is along the +y-axis.       Force is along the -y-axis.       Force is along the +z-axis.       Force is along the -z-axis.
	Q3.  For configuration (b), what is the force acting on the part of I1 to the left of the y-axis?       Force is zero.       Force is along the +y-axis.       Force is along the -y-axis.       Force is along the +z-axis.       Force is along the -z-axis.
