You are performing studies of the possibility of migrating birds using the Earth's magnetic field for navigation. To modify the magnetic field in the brain of a bird, you fit the bird with coils as "caps" and "collars" as shown in the figure below. The data on the coils indicate that they each have 210 n of resistance, a radius of 1.10 cm, and 50 turns of wire. The centers of the coils are separated by 2.15 cm. You wish to create an "Earth-like" magnetic field of 4.0 x 10-5 T at the midpoint of the axis between the coils. Given this data, you need to determine the voltage of the battery (in V) needed to power the coils. V
