Solenoids produce magnetic elds that are relatively
Chapter 22, Problem 97(choose chapter or problem)
Solenoids produce magnetic elds that are relatively intense for the amount of current they carry. To make a direct comparison, consider a solenoid with 55 turns per centimeter, a radius of 1.05 cm, and a current of 0.622 A. (a) Find the magnetic eld at the center of the solenoid. (b) What current must a long, straight wire carry to have the same magnetic eld as that found in part (a)? Let the distance from the wire be the same as the radius of the solenoid, 1.05 cm.
