Question details

34 Fig. 21-74 shows a Helmholtz coil, which consists of two identical circular coils having the same axis and separated by a distance equal to the radius of each coil. This arrangement produces a magnetic field that is fairly uniform over an extended region near the midpoint P between the coils. Therefore the Helmholtz coil is frequently used in experimental research requiring a moderately strong, nearly uniform, magnetic field over a fairly large, accessible region. Find the magnetic field at Pif r 33.0 cm and each coil consists of 36 turns of wire carrying a current of 4.00 A. Fig. 21-74 Helmhotz co
