Force on the current carrying conductor per unit length is given by:

Correct answer: D. IB sinϴ

  • A. IL sinϴ
  • B. ILB
  • C. IL
  • D. IB sinϴ

Explanation

IB sinϴ: This option suggests that the force on a current-carrying conductor per unit length is given by IB sinϴ. This is the correct expression. The force on a current-carrying conductor is proportional to the product of the current (I), the magnetic field strength (B), and the sine of the angle (ϴ) between the current direction and the magnetic field 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.
