Energy stored in a magnetic field is given by_
Correct answer: C. 0.5L * I^2
- A. LI^2
- B. 0.5L^2 * I
- C. 0.5L * I^2
- D. IL^2
Explanation
The energy stored in a magnetic field in an inductor is given by the formula W = LI2, where:* W is the energy stored,* L is the inductance of the coil, and* I is the current flowing through the coil.

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.
