Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

The problem is described in the attached image. It's regarding the calculation of the force due to a magnetic field over a conducting ring. I can calculate most of the problem. The force is basically: F = I * B * 2 * PI * R * SIN(X), where X is the angle between the magnetic field vector, and the vector with the direction of the electric current. Now, how do I calculate this angle? I've seen an answer that uses theta (provided by the exercise) as X, but why would theta be the angle between those two vectors, if it's only the angle between the magnetic vector and the vertical axis?
As shown below, a square loop of wire of side a moves through a uniform magnetic field of magnitude B perpendicular to the page at constant velocity, vector v, directed to the right.

I am not asking for the direction of current.)
A circular loop of wire sits face on to 2 tesla magnetic field that points into the page, as shown in the upper diagram at right.

(b) If the crank continues to turn the loop another quarter turn in 0.5 seconds in the same direction, until it looks like the bottom picture, what will be the average emf induced in the wire, and does the current in the wire flow in the direction of the arrow or in the opposite direction?
