**Question 4:**A loop carrying a current as shown rests in a uniform magnetic field directed to the right. If the loop is free to rotate about its center, describe what will occur. Explain your reasoning.---**Diagram Explanation:**The diagram shows a circular loop with a dot and cross at its center. The dot represents current coming out of the page, and the cross indicates current going into the page. The magnetic field is illustrated by three parallel arrows pointing to the right, indicating the direction of the uniform magnetic field (B field) around the loop.---**Analysis and Explanation:**In the scenario described, the loop is subject to the right-hand rule, which dictates the interaction between current and magnetic fields. As the current runs counterclockwise in the loop, different segments of the loop experience forces due to the magnetic field.Using the right-hand rule, the portion of the loop with current coming out of the page (dot) experiences a force upwards, while the portion where current goes into the page (cross) experiences a force downwards.These opposite forces create a torque on the loop, causing it to rotate. The loop will rotate such that the plane of the loop aligns perpendicular to the direction of the magnetic field, minimizing the loop's potential energy in the magnetic environment.

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.
