Find the force due to a current of 5 A passing through the element of length 2 cm and flux density of 12 Tesla.
Correct answer: B. 1.2 N
- A. 1 N
- B. 1.2 N
- C. 1.4 N
- D. 1.6 N
Explanation
Force due to a current element in a carrying conductor is given as F = ILB Where,'F' is the force'I' is the current'L' is the length of the conductor'B' is the strength of the magnetic field.= (5)(2 x 10-2)(12) = 1.2 N. Hence Option B is correct.

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.
