Point Pis on a perpendicular bisector of the line connecting the wires. In unit-vector notation, what is the net magnetic field at Pif the current in wire 2 is (a) out of the page and (b) into the page?
Equation 29-4 gives the magnitude Bof the magnetic field set up by a current in an infinitely long straight wire, at a point Pat perpendicular distance R from the wire. Suppose that point P is actually at perpendicular distance Rfrom the midpoint of a wire with a finite length L.Using Eq. 29-4 to calculate Bthen results in a certain percentage error. What value must the ratio exceed if the percentage error is to be less than That is, what gives
