Suppose you want to use a compass needle to measure the magnitude of a particular magnetic field. You plan to orient the field so it is perpendicular to the Earth's magnetic field. You have made a slight mistake, however, and instead the Earth's magnetic field makes an angle of 85° with respect to the field you want to measure. What is the percentage error in your observation?
