By how much is the approximation B = Honl in error at the center of a solenoid that is 17 cm long, has a diameter of 2 cm, is wrapped with n turns per meter, and carries a current I? Hint Review Section 12.6 Solenoids and Toroids for the derivation of the exact formula for a finitely-long solenoid. Note the terms that cancel out in calculation of percent error. Compared to the exact expression, the approximation B HonI is greater / by %.
