When a current-carrying conductor is placed in a magnetic field. It moves from a region of:
Correct answer: A. Stronger to a weaker field
- A. Stronger to a weaker field
- B. Remains stationary
- C. Weak to strong if the current is large
- D. All of these
Explanation
A current-carrying conductor placed in a magnetic field will move from a region of stronger to a weaker field. This is because the magnetic force on a current-carrying conductor is proportional to the strength of the magnetic field. The force is also in the direction of the magnetic field. If a current-carrying conductor is placed in a region of a stronger magnetic field, the force on the conductor will be stronger. This force will cause the conductor to move in the direction of the magnetic field, which is from the region of a stronger to a weaker 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.
