question 59

Multiple Choice

A long,straight wire with A long,straight wire with   current flowing through it produces magnetic field strength   at its surface.If the wire has a radius R,where within the wire is the field strength equal to   of the field strength at the surface of the wire? Assume that the current density is uniform throughout the wire.(μ<sub>0</sub> = 4π × 10<sup>-7</sup> T ∙ m/A)  A) 0.36 R B) 0.060 R C) 0.64 R D) 0.030 R current flowing through it produces magnetic field strength A long,straight wire with   current flowing through it produces magnetic field strength   at its surface.If the wire has a radius R,where within the wire is the field strength equal to   of the field strength at the surface of the wire?
