If a conductor of length 7m is placed in a magnetic field of strength 0.3 T carrying current 1 A, parallel to the field. What will be the force, acting on it, due to this magnetic field?
Correct answer: B. 0 N
- A. 7 N
- B. 0 N
- C. 3.1 N
- D. 2.1 N
Explanation
When the conductor is placed parallel to magnetic field, no force will act on it.

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.
