Magnetic Surround Wire Inductors

A Magnetic Ring Inductor is an electronic device that measures physical quantities such as current, voltage, and magnetic field by inducing a magnetic field. It consists of a magnetic ring, a coil, and a core. When a current passes through the coil, it generates a magnetic field that passes through the core and then back through the magnetic ring to the coil. This process of interaction between the current and the magnetic field in the coil creates an inductance, called a magnetic ring inductor.Magnetic loop Inductor

Magnetic ring Inductors are used in a wide variety of applications, such as electrical power, electronics, communications, and automotive. We will describe its applications in more detail below:

Measuring Current
Magnetic ring inductors can be used to measure DC, AC and pulse currents. In the field of electric power, magnetic ring inductors are commonly used for AC current measurement and power metering. In the field of communications, magnetic ring inductors are commonly used to measure RF currents.High Frequency Transformers

Measuring Voltage
Magnetic loop inductors can also be used to measure voltages. It is based on the principle of winding a secondary coil around a magnetic ring. When a section of the voltage to be measured is applied to the primary coil, a magnetic flux is generated inside the ring. This magnetic flux causes a potential difference within the secondary coil, thus measuring the voltage magnitude.Flat Inductor

Measuring Magnetic Fields
Toroidal inductors can also be used to measure magnetic fields. As the magnetic field passes through the magnetic ring, it creates a potential inside the coil, which measures the magnitude and direction of the magnetic field. In electronics, magnetic ring inductors are commonly used to measure magnetic fields in magnetic storage components.

Signal Filtering
Magnetic ring inductors can also be used for signal filtering, where signals of a specific frequency are passed through the coil, ring and core to achieve selective amplification or suppression of the signal to achieve the final signal filtering effect.

Adjusting the resonant frequency of radio transceivers
Magnetic ring inductors are one of the important components in the frequency converter of radio transceivers. The magnetic ring inductor can be adjusted by selecting different coil turns, core material and ring material to adjust its inductance value, thus achieving the resonant frequency of the radio transceiver.

Synchronous Motor Starting
Magnetic ring inductors are also often used for synchronous motor starting. During starting, the inductive effect of the magnetic ring inductor can limit the starting current of the motor to a safe range, which plays a very important role in protecting the motor.

Automotive Electronic Components
In the automotive industry, magnetic toroidal inductors are also frequently used in automotive electronic components such as braking systems, oxygen sensors, emission ducts and fuel systems.

Magnetic ring inductors are used in a wide variety of fields such as electrical power, electronics, communications, and automotive. They measure currents, voltages, and magnetic fields, are used for signal filtering and to regulate the resonant frequency of radio transceivers, and are also used in synchronous motor starting and automotive electronic components. Its important role in the modern field of science and technology is increasingly valued and developed.
