The correct answer is option 'C': The magnetic field inside the core of a toroid is constant.
Explanation:
To understand why the magnetic field inside the core of a toroid is constant, let's first understand what a toroid is. A toroid is a three-dimensional geometric shape that resembles a doughnut. It is formed by rotating a circle about an axis that is coplanar with the circle.
Magnetic Field in the Open Space Inside the Toroid:
The open space inside the toroid is referred to as the central region or the core. Due to the presence of a current-carrying wire wound around the toroid, a magnetic field is generated. The magnetic field lines produced by the current in the wire are concentrated inside the core. The magnetic field in this region is uniform and constant.
Magnetic Field in the Open Space Exterior to the Toroid:
The open space exterior to the toroid is referred to as the external region. In this region, the magnetic field lines spread out and weaken as they move away from the toroid. The magnetic field strength decreases with increasing distance from the toroid. Therefore, the magnetic field in the external region is not constant.
Magnetic Field Inside the Core of the Toroid:
The magnetic field inside the core of a toroid is constant due to the specific arrangement of the wire windings. The wire is wound in a tightly packed, continuous loop around the toroid's core. This arrangement ensures that the magnetic field lines are confined within the core and do not escape. The magnetic field strength inside the core remains constant throughout the volume of the core.
Conclusion:
In summary, the correct statement is option 'C': The magnetic field inside the core of a toroid is constant. The magnetic field is uniform and does not vary with position inside the core.
