Answer #1

given that dip angle is θ=79 deg

horizontal component of earth magnetic field is B_h=16μT

   magnitude of earth magnetic field is B=B_h tanθ

                                                           =16tan79

                                                           =82.312μT

Bats are capable of navigating using the earth's field-a plus for an animal that may fly great distances from its roost at night. If, while sleeping during the day, bats are exposed to a field of a similar magnitude but different direction than the earth's field, they are more likely to lose their way during their next lengthy night flight. Suppose you are a researcher doing such an experiment in a location where the earth's field is 50 μT at...
