The magnetic energy stored in an induction coil (choose the correct statement). |
Does not depend on magnitude of current depends on squared value of magnetic field Does not depend on self inductance of the coil Does not depend on area of coil |
depends on squared value of magnetic field |
The correct answer is Option (2) → depends on squared value of magnetic field Yes, the magnetic energy stored in an inductor is proportional to the square of the magnetic field. Magnetic field density $e_m=\frac{B^2}{2μ}$ |
