The torque in the coil can be increased by increasing:
Correct answer: D. All of above
- A. Number of turns
- B. Area of coil
- C. Current and magnetic field
- D. All of above
Explanation
The torque experienced by a coil in a magnetic field can be increased by increasing any or all of the following factors: a) Number of turns: Increasing the number of turns in the coil will result in a stronger magnetic interaction with the external magnetic field. This leads to an increase in the torque experienced by the coil. b) Area of the coil: A larger coil will intercept more magnetic field lines, resulting in a greater magnetic flux passing through the coil. As a result, the torque on the coil will increase. c) Current and magnetic field: The torque experienced by the coil is directly proportional to the product of the current passing through the coil and the strength of the external magnetic field. Increasing either the current through the coil or the strength of the magnetic field (or both) will result in a larger torque on the coil. In summary, all of the factors mentioned (number of turns, area of the coil, and current/magnetic field) contribute to increasing the torque experienced by the coil in a magnetic field.

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.
