The magnetic field out of the solenoid is:
Correct answer: A. Negligibly weak
- A. Negligibly weak
- B. Uniform
- C. Uniform and strong
- D. All of above
Explanation
Magnetic field outside of the solenoid is extremely weak and can be considered negligible. In many practical scenarios, especially for ideal solenoids with tightly wound coils and no external magnetic influences, the magnetic field outside the solenoid is indeed weak compared to the field strength inside the solenoid. The magnetic field lines tend to be more concentrated within the solenoid, and outside the solenoid, they spread out and weaken rapidly with increasing distance from the solenoid.

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.
