The magnetic field, B, produced in a solenoid depends on:
Correct answer: D. Its length, number of turns and current in it
- A. Its length
- B. Its length and current in it
- C. Its length and number of turns in it
- D. Its length, number of turns and current in it
Explanation
Inside a solenoid, B=μ0IN/Lwhere I is the current,N is the no. of turns L is length Therefore, magnetic field inside a solenoid depends on all these factors.

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.
