What is the magnetic field at any point in the open space inside the toroid?
Correct answer: A. zero
- A. zero
- B. one
- C. Depends on the current in the turns
- D. Depends on number of turns
Explanation
For an ideal toroid, the magnetic field outside the windings and in the central open space is zero because the magnetic field lines remain confined within the toroidal core. The field inside the windings depends on current and turns.
