A toroid is?I- A circular ring shape of a coil.II- A solenoid bent in shape of a circle.
Correct answer: C. Both I and II
- A. I only
- B. II only
- C. Both I and II
- D. None of these
Explanation
A toroid is a coil of wire wound in the shape of a donut or ring. It can be considered as a solenoid that has been bent into a circle.Subtag: Amperes Law and Determination of Flux Density

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.
