The magnetic field B inside a long ideal solenoid is independent of
Correct answer: B. The current
- A. The core material
- B. The current
- C. The spacing of the windings
- D. The cross-sectional area of the solenoid
Explanation
The magnetic field (\(B\)) inside a long ideal solenoid depends on certain factors while remaining independent of others.Factors affecting the magnetic field (\(B\)) inside an ideal solenoid:1. **Current (\(I\)):** The magnetic field inside an ideal solenoid is directly proportional to the current flowing through the solenoid (\(B \propto I\)).2. **Number of Turns per Unit Length (\(n\)):** It's also proportional to the number of turns per unit length (\(n\)) of the solenoid (\(B \propto n\)).#### Factors that the magnetic field (\(B\)) inside an ideal solenoid is independent of:Option (b) The current:** The magnetic field strength (\(B\)) inside an ideal solenoid is directly proportional to the current (\(I\)) passing through the solenoid.Correct Answer:(b) The current

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.
