If the direction of current in the conductor and the magnetic field are the same, in which way will the conductor move?
Correct answer: A. It will not move
- A. It will not move
- B. At an acute angle with the direction of current
- C. Perpendicular to the direction of current
- D. In the direction of current
Explanation
The force on a current-carrying wire in a magnetic field is given by F = ILBsinθ, where θ is the angle between the current and the field. If they are in the same direction, θ = 0°, and since sin(0°) = 0, the force on the conductor is zero, and it will not move.

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.
