Question

These questions refer to the expression for the magnetic field at the center of the square solenoid. Assume: for all coils, each side of the square a = 2.58 cm and the length of the solenoid L = 23.3 cm.
NOTE: Everything must be in MKS units!
NOTE: µo = 1.26x10-6 in MKS units (determined in question 1).

a) In procedure 1, you will plot Bmax vs. N, the number of turns of the coil. Suppose you set the current of I = 4.17 A, and vary the number of turns of the coil (with a and L the same for each coil). Find the slope of this straight line.
1 T/turn

b) In procedure 2, you will plot Bmax vs. I. Suppose you use a coil with 523 turns, and vary the current I. Find:
- n, the number of turns per length: 2 turns/m
- the slope of this straight line: 3 T/A

Explanation / Answer

a) slope = 1.26*10^-6*4.17 = 5.25*10^-6 T/turn n = 523/.233 = 2244.6 turns/s slope = 1.26*10^-6*2244.6 = 2.83*10^-3 T/A
