Question

Section 30,1 The Biot-Savart Law
1. Review. In studies of the possibility of migrating
birds using the Earth's magnetic field for navigation,
birds have been fitted with coils as "caps" and "col-
lars as shown in Figure P30.1. (a) If the identical coils
have radil of 1.20 cm and are 2.20 cm apart, with 50
turns of wire apiece, what current should they both
carry to produce a magnetic field of 4.50 X 10-5T
halfway between them? (b) If the resistance of each
coil is 210 , what voltage should the battery supply.
ing cach coil have? (c) What power is delivered to
Cách coil
