The force on a wire is a maximum of 7.33E-2 N when placed between the pole faces of a magnet. The current flows horizontally to the right and the magnetic field is vertical. The wire is observed to "jump" toward the observer when the current is turned on. If the pole faces have a diameter of 12.9 cm, estimate the current in the wire if the field is 0.111 T.

If the wire is tipped so that it makes an angle of 10.6° with the horizontal, what force will it now feel?
