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.
The current density in a very long hollow cylindrical conductor of radius a and b, with a < b, has the direction of the cylinder axis, with modulus given by
J = J0(r2/ab)
where J0 is a positive constant and r is the distance from the axis of the conductor. Calculate the magnetic field for a < r < b.
I = 7 A current flows from the infinitely long wire along the y axis that intersects the z axis at the point C (0,0,8) in the upper half space, which is the empty space.
If z <0 half space, it is made of material with relative magnetic permeability µr = 7.
Write the sum of the components( Hx + Hy + Hz )of the magnetic field H [A / m] vector at point A (-2, -4,0-) (in half space z <0) in terms of the given magnitudesnumerically.
