SUMMARY
The magnetic field (B field) inside a toroid is not constant; it varies with the radius. According to Ampère's Law, the relationship is defined as B(2πr) = μ₀NI, where N represents the number of turns and μ₀ is the permeability of free space. The field strength is stronger on the inner edge of the toroid and weaker on the outer edge, confirming that the B field changes within the structure.
