What will be the energy stored in an inductor of length 2m if a current of 10A passes through it:
Correct answer: B. 100 J
- A. 10 J
- B. 100 J
- C. 200 J
- D. 50 J
Explanation
Okay, now that we know the inductance (L = 2 H), we can calculate the energy stored.Using the formula:CopyU = (1/2) * L * I^2We have:CopyU = (1/2) * 2 H * (10 A)^2 = 100 JTherefore, the energy stored in the inductor is b) 100 J.

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.
