Answer:
9.916\times 10^{-4}T
Explanation:
Diameter of toroid is 15 cm =0.15 m
So length of the toroid is
Number of turns of the toriod is given as 555
Current through the toroid is 0.670 A
Magnetic field

Answer:
We first to know that if the wheel rotates from rest means that at t=0 the velocity and the angle rotated is 0.
Then, we know:
Integrating 2 times, we have:
For the first 27.9 s, we have:
w = 37.107 rad/s
angle = 517.6426 rad
For the next seconds, according to the text, the angular velocity is constant so
w = 37.107 rad/s and hence, integrating:
Then, the time remaining is:
53.5 - 27.9 = 25.6
So for the next 25.6 seconds we have:
Finally, we add the 2 angles and we have as a result:
