A toroid having 200 turns caries a current of 1 A. The average radius of the toroid is 10 cm. The magnetic field at any point in the open space inside the toroid is
Options
(a) 4×10⁻³ T
(b) zero
(c) 0.5×10⁻³ T
(d) 3×10⁻³ T
Correct Answer:
zero
Explanation:
Magnetic field at any point in the open space inside the toroid is zero, because the amperean loop enclose net current equal zero.
