A rectangular loop is being pulled out of a uniform magnetic field as shown. The current in the wire is at a constant 2 amps while it is being pulled out of the magnetic field.  What is the force that you must apply in order to keep the loop moving at a constant speed? (I believe that this is all the info needed to solve the problem, if not please let me know what other info is needed).

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.
