Electromagnetic question
Consider a hollow cylindrical surface centered on the z-axis with radius r = a, carrying a uniform surface current density Jsa = 5 af A/m. Additionally, there is a second cylindrical surface with radius r = b (b > a), which carries a current density Jsb = 4 az A/m. Calculate the magnetic field intensity H(r) for the following regions:
1. For 0 < r < a: Determine H(r) using the given parameters.
2. For a < r < b: Calculate H(r) using the given parameters.
3. For r > b: Find H(r) using the given parameters.
In the upper half space, which is the empty space, I = 7 A current flows from the infinitely long wire along the y axis that intersects the z axis at the point C (0,0,10).
Half-space z <0 is from a material with relative magnetic permeability µr = 5.
1. Write numerically the sum of the components (Hx + Hy + Hz) at the point A (-5, -5,0+) of the magnetic field H [A / m] vector in terms of the given magnitudes (in the half space z> 0).
2.Write numerically the sum of the components (Hx + Hy + Hz) at the point A (-2, -4,0-) of the vector magnetic field H⃗[A / m] in terms of the given magnitudes (in the half-space z <0).
There are point loads Q1= 4, Q2=9 and Q3=4 at points A(-7,0), O(0,0) and B (4,0) in the OXY plane, respectively. Write the value of the y-component of the electric field in terms of ke numerically at the point P(0, 13) on the-axis.
