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

### Magnetic Field in a Coil Experiment

We are going to look at the specific case of a magnetic field in a coil (Section 12.4 in the OpenStax textbook). The equation for that works out to:

\[
B = \frac{\mu_0 IN}{2R}
\]

In Part 1 we are going to keep the Number of Loops (\(N\)) constant with a value of 14.0. The radius (\(R\)) will be constant and have a value of 7.00 cm as well as the other parts that are just numbers (like 2 and \(\mu_0\)).

You will make a graph where the **y axis** will be \(B\) (Magnetic Field) and the **x axis** will be \(I\) (Current). In LoggerPro the magnetic field axis will be measured in mT (milliTesla). You'll need to convert your answer into mT/A.

#### What do you predict will be the **magnitude of the slope** of the line for this graph?
*Hint: Think about what the slope of the line represents and how you can find it from constant values.*

**Your answer should include:**
**3 Decimal Places**
