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

B(2 pi r) = uo i = uo (J pi r^2)

Magnetic field, B = μo Jr/2

Explanation:

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
