B. Heat goes from the drink to the ice
Answer:
B = 4.323 T
Explanation:
We are given;
Inner radius; r_i = 0.7 m
Number of turns; N = 890 turns
Current; I = 17 KA = 17000 A
Formula for the magnetic field inside the toroid along the inner radius is given by;
B = (μ_o × N × I)/(2πr)
μ_o is vacuum of permeability with a constant value of 4π × 10^(-7) H/m
Plugging in the relevant values, we have;
B = (4π × 10^(-7) × 890 × 17000)/(2 × π × 0.7)
B = (2 × 10^(-7) × 890 × 17000)/(0.7)
B = 4.323 T
