Transcribed Image Text:**Title: Analysis of Magnetic Field in an Infinitely Long Current-Carrying Cylinder**
**Objective:**
To determine the magnetic field (\(\mathbf{H}\)) inside and outside an infinitely long cylinder that carries current, and calculate the curl of \(\mathbf{H}\) in both scenarios.
**Problem Description:**
Consider an infinitely long cylinder aligned along the z-axis. The cylinder has a radius \(a\) and carries a current characterized by the current density \(\mathbf{J} = \frac{I}{\rho} \mathbf{a}_z\), where \(I\) is the current carried by the cylinder and \(\rho\) represents the radial distance from the axis.
**Questions to Address:**
a. Determine the magnetic field \(\mathbf{H}\) outside the cylinder.
b. Calculate the magnetic field \(\mathbf{H}\) inside the cylinder.
c. Find the curl of the magnetic field, \(\nabla \times \mathbf{H}\), for both scenarios (a and b).
**Approach:**
- Apply Ampère's Law to find the expressions for the magnetic field in the required regions.
- Use the right-hand rule to determine the direction of the magnetic field.
- Evaluate \(\nabla \times \mathbf{H}\) using vector calculus.
**Outcome:**
The analysis will assist in understanding how the distribution of current affects the surrounding magnetic field in an infinite cylindrical conductor, which is a fundamental concept in electromagnetism with applications in designing devices like solenoids and inductors.
