Chapter 29, Problem 14P
Equation 29-4 gives the magnitude B of the magnetic field set up by a current in an infinitely long straight wire, at a point P at perpendicular distance R from the wire. Suppose that point P is actually at perpendicular distance R from the midpoint of a wire with a finite length L. Using Eq. 29-4 to calculate B then results in a certain percentage error. What value must the ratio L/R exceed if the percentage error is to be less than 1.00%? That is, what L/R gives

In Fig. 29-37, point P is at perpendicular distance R = 2.00 cm from a very long straight wire carrying a current. The magnetic field set up at point P is due to contributions from all the identical currentlength elements along the wire. What is the distance s to the element making (a) the greatest contribution to field and (b) 10.0% of the greatest contribution?
(Please type answer no write by hend)
To solve problems, you will need to know the formula and orientation of the magnetic field with respect to the current.
The formula, B=u0I/2piR, describes the magnetic field B at a distance R from a straight wire carrying current I. u0= 4π*10-7 N/A2 and is called the permeability of free space. Magnetic field is in the units of Tesla (T) and has direction.
The field lines "curl" around the wire on a plane perpendicular to the wire as shown below. The direction of this magnetic field "curl" is in the direction of [ans1]
