Is the current large when the inductor stores large energy

When does the energy stored by an inductor stop increasing?

The energy stored by the inductor increases only while the current is building up to its steady-state value. When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand.

How does an inductor store energy?

An inductor stores energy in its magnetic field. As the current through the inductor increases, it forces the magnetic lines of force to expand against their natural tendency to shorten. This expansion stores energy in the magnetic field, similar to how a rubber band stores energy when stretched.

How is the energy stored in an inductor calculated?

The energy stored in the magnetic field of an inductor can be written as E = 0.5 * L * I^2, where L is the inductance and I is the current flowing through the inductor.

How does a Magnetic Inductor increase if a current is constant?

When the current remains constant, the energy stored in the magnetic field is also constant. 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.

What happens when an inductor reaches a steady-state value?

When the current in a practical inductor reaches its steady-state value of Im = E/R, the energy stored by the inductor stops increasing. The magnetic field ceases to expand, the voltage across the inductance drops to zero, and the power becomes zero.

What happens when an inductor is switched into a circuit?

When an inductor is switched into the circuit, the current starts to increase quickly, but the increasing magnetic field impedes the current. As the current increases, the magnetic field gets stronger. When the inductor is disconnected from the circuit, the decrease in current allows the magnetic field to collapse.
