Which of the following statement is true?i) Toroid is a solenoid bent into circular pathii) Solenoid is a toroid in open
Correct answer: A. i is true
- A. i is true
- B. ii is true
- C. Both a and b
- D. None of these
Explanation
Toroid: A toroid is a coil of wire wound in the shape of a donut or ring. It is essentially a solenoid that has been bent into a closed loop.Solenoid: A solenoid is a coil of wire wound in the shape of a helix. It is a cylindrical coil with a uniform magnetic field inside it.Therefore, statement i) is true, while statement ii) is incorrect. A solenoid is not a toroid in an open form.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
