a thin straight wire carrying a current I is placed along the x axis as shown in figure
evaluate the magnetic field at point p. note that we have assumed that the leads to the end of the wire make cancelling contributions to the net magnetic field at the point p
Exercise 2: Magnetic Field due to a Finite Straight Wire A thin, straight wire carrying a current I is placed along the x-axis, as shown in Figure 2. Evaluate the magnetic field at point P. Note that we have assumed that the leads to the ends of the wire make cancelling contributions to the net magnetic field at the point P. 0
