The force on the conductor will be when there is magnetic field into the conductor:
Correct answer: D. 45°
- A. 90°
- B. 0°
- C. 120°
- D. 45°
Explanation
Option B is correct.The force on the conductor will be zero when there is magnetic field into the conductor. The magnetic force on a current-carrying conductor is given by the following equation: F = BIL sin θ where: θ is the angle between the direction of the current and the direction of the magnetic field (°) When the magnetic field is parallel to the conductor, θ = 0 and the magnetic force is zero. Here is a mathematical explanation: If the magnetic field is parallel to the conductor, then the direction of the magnetic field lines will be parallel to the direction of the current. In this case, the magnetic force will be zero. For this to happen, the condition is sin0° =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.
