Understanding Analog Circuits

At Sag Harbor Industries, one of the products that we manufacture and supply to various industries is a magnetic coil. Magnetic coils are a key component in what is known as an analog circuit. An analog circuit can be found in a lot of older technology, like TV or radio antennas. We still use analog technology, but things are becoming increasingly digital. However, very common technology that we use every day like the car radio harnesses analog signals to perform its function. In this post, we’ll take a quick look at how an analog circuit works and why a magnetic coil is so important to the process. Let’s take a closer look!

Depending on the device, an analog circuit can either be very complex or very simple. A series of caps, resistors, coils, diodes and other basic electronic components need to be arranged together in a very specific way to create a functional device. In the midst of this set up, a magnetic coil is placed to transfer the electric current and create a magnetic field. This current passing through the magnetic coil is increased by the number of times the wire is turned, meaning that the more times the wire is turned the greater the size of the magnetic field will be. The magnetic core at the center of the coil is what helps to create such a strong magnetic field in the surrounding area. The point of a magnetic coil is usually to exert mechanical force on something so that the desired reaction happens or the desired machinery is activated. A time varying element can be added to the magnetic coil to create pulses of voltage for intermittent activation.

This is a very basic overview of how a magnetic coil functions in a magnetic circuit. There are many more complexities, but suffice it to say that a magnetic coil is very important to many analog functions.
