A current carrying conductor experiences maximum magnetic force in a uniform magnetic field when the conductor is placed
Correct answer: B. perpendicular to the magnetic field
- A. parallel to the magnetic field
- B. perpendicular to the magnetic field
- C. at an angle of 30° to the magnetic field
- D. at an angle of 60° to the magnetic field
Explanation
The correct answer is that the conductor experiences maximum magnetic force when it is perpendicular to the magnetic field. This is because the magnetic force on a current-carrying conductor is given by F = BIL sin(θ), where θ is the angle between the conductor and the magnetic field. The maximum value of sin(θ) is 1, which occurs when θ is 90 degrees. Thus, Option B is correct. Options A, C, and D are incorrect because they involve angles where the sine value is less than 1, resulting in a reduced magnetic force.

About Magnetic Flux Density
Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
