Applications of Inductors
Tuning Circuits
Inductors are used in tuning circuits to select the desired frequency. In a tuned circuit, a capacitor is connected along with the inductor, either in parallel or series. The frequency of the tuning circuit at which the capacitive reactance is equal to the inductive reactance (XC = XL) is called 'Resonant Frequency'. Electronic devices such as radio tuning circuits and television use capacitors along with the inductor to modify the frequency and select within multiple channels of frequency.
Sensors
Inductive proximity sensors are very reliable in operation and are a contactless sensor. An inductive sensor is a non-contact type of sensor, helpful in the detection of metallic objects. It can sense ferrous as well as non-ferrous materials. The sensing range is up to 100 mm.
Energy Storage
Inductors can store energy for a small period of time because the energy which is being stored as a magnetic field will be gone when the power supply is removed. The energy stored in an inductor is due to the magnetic field created by the current flowing through it. As the current through the inductor changes, the magnetic field also changes, and energy is either stored or released.
Induction Motors
In induction motors, the shaft in the motor will rotate due to the presence of the magnetic field produced due to alternating current. An induction motor works by using electromagnets to create a rotating magnetic field. This field then induces an electric current in the rotor, which creates its own magnetic field. The interaction between the two fields causes the rotor to turn, effectively rotating around the motor.
Transformers
A combination of multiple inductors with a shared magnetic field can be designed into a transformer. Transformers do not rely on the inductive properties of an electric circuit to transfer energy. Instead, they use magnetic induction, making them more efficient and allowing them to transfer higher voltages with less loss.
Filters
Inductors when combined with capacitors will be used as filters. LC filters refer to circuits consisting of a combination of inductors (L) and capacitors © to cut or pass specific frequency bands of an electric signal. Capacitors block DC currents but pass AC more easily at higher frequencies. Conversely, inductors pass DC currents as they are, but pass AC less easily at higher frequencies.

Safety Precautions For Using Inductors
Automatic Discharge
Automatic shorting devices like varistors and freewheeling diodes can be used to provide additional current paths when the excitation is interrupted. This way, a path is provided to the inductor to release its energy without forming arcs at the circuit break point.
Connections
When an excited inductor loses connection to the supply, it quickly breaks its magnetic fields and tries to continue the connection to the supply with the converted energy. This energy can cause destructive arcing around the point where the connection is lost. Thus, the connectivity of the circuit must be continuously observed.
Eddy Currents
Self-induction and mutual induction due to the inductor's magnetic field can cause eddy currents to flow in the body of the inductor and any nearby conductors. These are undesirable because they produce mechanical stress, heat, and energy losses. Therefore, considerable mechanical and electrical support should be provided to dissipate any stress or heat produced safely.
Verify De-Energization
Another safety consideration is to verify the de-energized state of inductors. Any residual energy in inductors can cause sparks if the leads are abruptly disconnected.
