When a current carrying conductor is placed in a magnetic field. It moves from a region of
Correct answer: B. weak to strong field
- A. stronger to weak field
- B. weak to strong field
- C. strong to weak if current is large
- D. weak to strong if current is large
Explanation
B is the correct answer.According to Fleming's left-hand rule, when a current carrying conductor is placed in a magnetic field, a force is exerted on it perpendicular to both the current direction and the magnetic field direction. This force causes the conductor to move from a region of weaker magnetic field to a region of stronger 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.
