Find the magnetic field intensity at P (4,3,1) due to an infinite current ine having 3n Ampere current flowing in negative z axis hint H= the solution steps: 1. the intersection between the current ine and the vector pis at x, y.z k intersection). ly intersection). [z intersection) 2. The components of the vector pin cartesian coordinate system ax, ay, az x.compl.ly.compl(z.comp) 3. the perpendicular distance between the point P.and the line equals [roo_magnitude] 4. In the cylindrical coordinate system; The components of the unit vector in the direction of the magnetic field at the point P is ap, @g. az [roo_unit). [phi_unit)lz unit). 5. In the Cartesian coordinate system; The components of the unit vector in the direction of the magnetic field at the point P is x, y. z 6. the magnitude of the magnetic field H at the point P equais (H] 7. (True or false) H is measured in Wb/m2, insert the letter t for true and insert the letter f for false. ( not case sensitive) (H_units)
