If a current carrying conductor is placed at right angle to the magnetic field, then the forceexperienced by the conductor will

Correct answer: B. be maximum.

  • A. be zero.
  • B. be maximum.
  • C. remain constant.
  • D. vary unpredictably.

Explanation

* The force (F) experienced by a current-carrying conductor in a magnetic field is given by the formula: F = I * L * B * sin(theta) Where: * I is the current in the conductor. * L is the length of the conductor. * B is the magnetic field strength. * theta is the angle between the direction of the current and the direction of the magnetic field. * When the conductor is placed at a right angle to the magnetic field, the angle (theta) is 90 degrees. * The sine of 90 degrees (sin 90°) is 1. * Substituting this into the formula: F = I * L * B * 1 F = I * L * B * Since the maximum possible value for sin(theta) is 1, the force is at its maximum when the conductor is perpendicular (at a right angle) to the magnetic field.

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.
