Birds and magnetic fields
WebTo 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 o f resistance, a radius of 1.10 cm, and 50 turns of wire. The centers of the coils are separated by 2.40 cm. You wish to create an "Earth-like" magnetic ... WebBut the researchers exposed them to a magnetic field that matched the coordinates of Neftekamsk, Russia—2,500 km (1,600 mi) northeast from their real location. This city was chosen for two reasons: First, it is far from anywhere the birds would go, and second, it would make them fly in a very different direction from their typical migrating path.
