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.

**Current Attempt in Progress**

A loop of wire has the shape shown in the drawing. The top part of the wire is bent into a semicircle of radius \( r = 0.30 \) m. The normal to the plane of the loop is parallel to a constant magnetic field (\( \varphi = 0° \)) of magnitude 0.77 T. What is the change \( \Delta \Phi \) in the magnetic flux that passes through the loop when, starting with the position shown in the drawing, the semicircle is rotated through half a revolution?

**Diagram Explanation:**

The diagram illustrates a loop of wire, where the top part forms a semicircle. Specifically:

- The semicircle is of radius \( r = 0.30 \) m.
- The magnetic field \( \mathbf{B} \) is directed into the plane of the paper, indicated by the symbols '×'.
- Initially, the normal to the plane of the loop (perpendicular to the surface area of the semicircle) is parallel to the magnetic field direction.

The problem involves calculating the change in magnetic flux \( \Delta \Phi \) through the loop when the semicircle is rotated through half a revolution (180 degrees).

**Input Section:**

There is a placeholder for recording the change in magnetic flux (\( \Delta \Phi \)) where you can select the unit of measurement and input the calculated value.
