The property of inductor current continuity implies that the current flowing through an inductor cannot change instantaneously due to the energy stored in the magnetic
Energy stored in the inductor: U = 1/2 L I2 When the switch is opened, this energy is dissipated in the resistor. An inductor doesn’t like change!!! When the switch is opened, the inductor will try to maintain the current that was flowing through it before the switch is opened.
The article discusses the concept of energy storage in an inductor, explaining how inductors store energy in their magnetic fields rather than dissipating it as heat. It covers the mathematical formulation for calculating stored energy, the behavior of ideal and practical inductors, and provides an example calculation to illustrate the concept.
Figure 1 Determining the energy stored by an inductor In resistance circuits where the current and voltage do not change with a change in time, the energy transferred from the source to the resistance is W = Pt = VIt.

Consider a toroid magnet, the B field is, B = μ 0NI/2πr. The energy is, 2 ⎜ 2 πr ⎟ ⎝ ⎠ by value at center of coil. Initially, the inductor behaves like an open switch. After a long time, the inductor behaves like an ideal wire. Initially, the inductor behaves like a current source. After a long time, the inductor behaves like an open switch.
When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up to its steady-state value.
The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up to its steady-state value. When the current remains constant, the energy stored in the magnetic field is also constant.
