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 direction of current.
- C. Perpendicular to direction of current.
- D. In direction of current.
Explanation
The correct option is A It will not move. The direction of the force on a conductor placed in a magnetic field is given by Fleming's left-hand rule. According to this rule, holding the forefinger, middle finger, and thumb of the left hand in mutually perpendicular directions, the forefinger indicates the direction of the magnetic field and the middle finger, the direction of the current, then the thumb will indicate the direction of the force which results in the motion of the conductor. However, this force is not experienced when the current flows in the direction of the magnetic field. Here, the direction of the current in the conductor and the magnetic field are the same, so, the conductor will not experience any force. Hence, it will not move in any direction.

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.
