Two identical coils are suspended from a string and are swinging forth and back as pendula as shown below. Coil 1 swings in the plane of the coil, coil 2 swings in the plane perpendicular to the coil. A current can be induced:
a) In both coils as they swing in Earth magnetic field.
b) Only in coil 1
c) Only in coil 2
d) In neither coil
e) It depends on the direction of the Earth field relative to the coils
