An infinitely long, straight, cylindrical wire of radius R R has a uniform current density → J = J ^ z J→=Jz^ in cylindrical coordinates. What is the magnitude of the magnetic field at some point inside the wire at a distance r i < R ri
An infinitely long, straight, cylindrical wire of radius R R has a uniform current density → J = J ^ z J→=Jz^ in cylindrical coordinates. What is the magnitude of the magnetic field at some point inside the wire at a distance r i < R ri
Answer:
B(2 pi r) = uo i = uo (J pi r^2)
Magnetic field, B = μo Jr/2
