A current-carrying conductor is placed in a uniform magnetic field Parallel to it. The magnetic force experienced by the conductor is
Correct answer: D. F=0
- A. F=BIL
- B. F=BLsinθ/I
- C. F=I/BL sin0
- D. F=0
Explanation
The correct formula is F = BIL sinθ When a current-carrying conductor is parallel to the magnetic field the angle θ (that is the angle between the conductor and magnetic field) equals zero. So, sinθ = 0 F = BIL sinθ = BIL x 0 = 0 Force = 0

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.
