Current Attempt in Progress
In the figure, a long, straight copper wire (diameter 2.49 mm and resistance 1.22 Q per 370 m) carries a uniform current of 28.0 A in the
positive x direction. For point Pon the wire's surface, calculate the magnitudes of (a) the electric field E→, (b) the magnetic field B
→, and (c) the Poynting vector S→, and (d) determine the direction of S→.

Expert Solution
Step 1
Concept:
Given;
Diameter= 2.49 mm
Thus, radius (r)=1.245 mm
Resistance = 1.22 ohm
Length (L)= 370 m
Current (I) =28 A
To determine the Electric field the formula used is
To determine the Magnetic Field
And the formula to determine the poynting vector is
Step by step
