Answer:
Explanation:
This depends on where you are.
The YMCA where I grew up was affordable. Very. Or my mother would not have let me go.
Answer:
(a) 4.27 x 10^-4 Telsa
(b) 3.28 x 10^-4 Telsa
Explanation:
side of square, a = 5.49 cm
inner radius, r = 18.1 cm = 0.181 m
number of turns,N = 450
current, i = 0.859 A
(a)
The magnetic field due to a solenoid due to inner radius is
![B = \frac{\mu_{0}Ni}{2\pi r_{inner}}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B%5Cmu_%7B0%7DNi%7D%7B2%5Cpi%20r_%7Binner%7D%7D)
![B = \frac{4\pi\times 10^{-7}\times 450\times 0.859}{2\pi \times 0.181}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B4%5Cpi%5Ctimes%2010%5E%7B-7%7D%5Ctimes%20450%5Ctimes%200.859%7D%7B2%5Cpi%20%5Ctimes%200.181%7D)
B = 4.27 x 10^-4 Telsa
(b)
The outer radius is R = 18.1 + 5.49 = 23.59 cm = 0.236 m
The magnetic field due to the outer radius is
![B = \frac{\mu_{0}Ni}{2\pi r_{outer}}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B%5Cmu_%7B0%7DNi%7D%7B2%5Cpi%20r_%7Bouter%7D%7D)
![B = \frac{4\pi\times 10^{-7}\times 450\times 0.859}{2\pi \times 0.236}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B4%5Cpi%5Ctimes%2010%5E%7B-7%7D%5Ctimes%20450%5Ctimes%200.859%7D%7B2%5Cpi%20%5Ctimes%200.236%7D)
B = 3.28 x 10^-4 Tesla
