Anytime a scientific theory is challenged does it mean that its not a good theory

A toroidal inductor has a circular cross-section of radius a a. The toroid has N turns and radius R. The toroid is narrow (a≪R), so the magnetic field inside the toroid can be considered to be uniform in magnitude.

A quarterback throws a football with an initial velocity v at an angle θ above horizontal. Assume the ball leaves the quarterback's hand at ground level and moves without air resistance.
