Magnets in Wireless Charging
Did you know that wireless chargers can be used beyond portable and wearable devices for consumers? In fact, wireless charging can be advantageous in a variety of industrial applications including electric vehicles, drones, factory automation, handheld terminals, contactless charging of subsea vehicles, and much more!
Wireless charging, where energy transfers from a power source to another device without using wires, has become the way of the future, including industrial settings! According to Allied Market Research, “The global wireless charging market size was valued at $6.51 billion in 2018, and is expected to reach $40.24 billion by 2027, growing at a CAGR of 22.2% from 2020 to 2027.” As the wireless market is growing, it is best to get ahead and adapt to the way of the future.
How it Works
We know that wireless charging consists of charging devices hands-free by only plugging in the charger, but have you ever wondered how it works? There are two types of wireless charging: resonance and inductive charging. Both types of wireless chargers involve transferring power from a charger to a device through a magnetic field using coils. The interaction between the transmitter coil, located in the charger, and the receiver coil, located in the device, generates a magnetic field. The main difference between the two types of chargers is that resonance charging works without the charger and device being directly in contact, it just has to be within range; whereas, with inductive charging, it requires the device and the charger to touch. Inductive charging tends to have a higher transfer efficiency, but you can also increase the efficiency of resonance charging by adding more coils.

LiveScience explained the inside of charging pads like this: “Essentially, wireless charging uses a loop of coiled wires around a bar magnet — which is known as an inductor. When an electric current passes through the coiled wire, it creates an electromagnetic field around the magnet, which can then be used to transfer a voltage, or charge, to something nearby.” Overall, wireless charging is not only more efficient than wired charging, it is more cost-effective too. All you have to do is set your device on top or near the charger for it to work.Industry Uses
Now that we have a basic understanding of how wireless charging works, let’s dive into ways that wireless charging can be beneficial to your business. Whether you are in the electronics industry, automobile industry, or beyond, you can implement wireless charging. Here are some examples:- In the technology industry, you can use wireless charging to charge phones, watches, tablets, laptops, and more!
