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.

Question

**Electromagnetism: Calculating Magnetic Field Near Parallel Wires**

**Problem 93:**

A circuit with current \( I \) has two long parallel wire sections that carry current in opposite directions. Find the magnetic field at a point \( P \) near these wires that is a distance \( a \) from one wire and \( b \) from the other wire, as shown in the figure below. Assume \( I = 2 \, \text{A} \), \( a = 5 \, \text{cm} \), \( b = 3 \, \text{cm} \).

**Diagram Explanation:**

The diagram shows two wires with currents flowing in opposite directions. The point \( P \) is indicated by a dot and is located at the end of a right triangle:

- The horizontal leg is labeled as \( a \), representing the distance from the first wire to point \( P \).
- The vertical leg is labeled as \( b \), representing the distance from the second wire to point \( P \).

The distance measurements \( a \) and \( b \) are part of a right triangle configuration used to determine the position of point \( P \) relative to the wires.

This setup is used to calculate the resultant magnetic field at point \( P \) by considering the contributions from each wire.
