Question

9. On Thursday (June 6th), long solenoid is simply B uoln with I the current passing through the wire and n the coil density (number of turns per unit length). If the solenoid is of a finite length L, the result of the magnetic have shown that the magnetic field at the central axis of an infinitely we - field is found to be B HoIn(sin 02-sin01), where 0 x 1arctan L-x 02 arctan = a a considering: X Make sketches for B as a function of x, considering L= 5cm and: (5 points) = 5 mm (a) (b) a 1mm (5 points) (c) a 0.1 mm (5 points)
