If a conductor carrying current I is placed in uniform magnetic field B, It experiences a magnetic force F. The direction of this force F.
Correct answer: D. Is perpendicular to both current I and magnetic field B
- A. Is parallel to current I only
- B. Is perpendicular to current I only
- C. Is perpendicular to magnetic field B only
- D. Is perpendicular to both current I and magnetic field B
Explanation
The correct answer is that the force is perpendicular to both the current I and the magnetic field B. This is determined using the right-hand rule, where the thumb represents the direction of the current, the fingers represent the direction of the magnetic field, and the palm faces the direction of the force.The other options are incorrect because they fail to recognize the dual perpendicular nature of the force direction concerning both the current and the 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.
