    에너지를 전기로 바꾸는 자석

    19세기, 자기장과 전기장 간의 관계가 발견되었을쯤, 현재 무선충전의 기반이 되는 전자기장을 이용한 발명품이 등장했습니다.

    무선충전기 속 자석

    자성체는 철 등 금속체를 당기는 특성을 지닙니다. 자석의 접착력은 활용한 무선충전기를 비롯한 많은 제품에 적용되고 있습니다.

    그렇다면, 자석은 전자기기에 유해한 것인지?

    자석은 컴퓨터를 비롯한 전자기기에 널리 쓰이고 있지만, 크게 걱정할 수준은 아닙니다. 자석은 흔히 가전제품에 가장 많이 활용되고, 적절한 설계와 설치로 안전하게 사용할 수 있습니다.

    자석은 무선충전에 영향을 주는 것인지?

    대중에 흔히 무선충전으로 알려진 방식은 자기장을 통해 전기를 무선으로 전달하는 "자기유도 방식"입니다. 따라서 자석은 무선충전 기능 장애를 일으키거나 무선충전기와 충전대상 간 올바른 위치선정에 영향을 줍니다.

    이는 애플이 자사의 아이폰과 충전기 간에 "충전기 표면의 자석, 스마트폰의 자석 케이스, 다른 이물성 물체" 을 피하도록 한 이유와 같습니다.

    그럼에도 자성체가 있는 무선충전기를 쓰는 이유는 무엇인지?

    자성체가 있는 무성충전기는 휴대전화와 충전기 간 위치를 자동으로 정렬하고, 일정하고 안정적으로 위치를 유지할 수 있습니다.

    반면, 기존 자기유도 방식의 일반적인 무선충전기는 휴대전화와 충전기 간 접착이 요구되지만, 자동차 등 사용 중 진동 등이 발생하는 사용환경에서 위치정렬이 쉽게 틀어지게 됩니다.

    Do Magnets Affect Wireless Charging Your Phone?

    It is a common and widespread notion that magnets are harmful to our electronic devices. Many of us accept that magnets can erase or ruin the data on a hard disc or affect your phone’s GPS, but are magnets really harming our electronics?

    In actuality, magnets are relatively commonplace in the equipment we use every day, from our speakers to the washing machine. Magnets also exist in our personal electronic equipment, such as earphones and even our mobile phones.

    With the increasing popularity of wireless charging, many ask the question, do magnets affect wireless charging?

    What Role Do Magnets Play in Wireless Charging?

    Magnets Turn Energy into Electricity

    As you may know, magnets make wireless charging possible, as they use a magnetic field to transfer power. When scientists in the 19th century discovered the relationship between magnetics and electricity, Nikola Telsa and other inventors began to create electronic devices using electromagnetism, laying the foundations for wireless charging.

    Magnets in Wireless Chargers

    Magnetic materials have the strength to attract or pull metals, like iron and steel. This inherent quality of magnets has been used in many products, including magnetic wireless chargers.

    Though you may have never considered the combination, magnetic wireless chargers are one of the best implementations of wireless charging. Your phone (with a phone case) is attracted to the charger without you pulling them together or extra materials. How great is it? We’ll get to that later.

    Do Magnets Damage Electronics?

    Magnets are widely used in electric devices, electronics, computers, etc. But there isn’t too much to worry about. Why? Magnets inside electronics are usually household level, safe to use. Moreover, as long as those magnets are properly installed, you can put them to good use.

    Will Magnets Affect Wireless Charging?

    Wireless charging, also known as inductive charging, uses magnetic fields to transfer electricity wirelessly. Thus, magnets can cause interference with wireless charging, making it difficult for the two to pair together. This is why Apple suggests avoiding “magnetic mounts, magnetic cases, or other objects between your iPhone and the charger.”

    However, reliable magnetic wireless charger manufacturers, including PITAKA, position magnets that avoid interference between the charging coils and the phone. Also, specifically placing metal inside the phone case or on the phone further avoids affecting the intricate workings of a phone.

    Why Should You Choose Magnetic Wireless Chargers?

    Magnetic chargers auto-align your device on the mount, ensuring a constant and stable charge. Magnetic wireless chargers are also more practical. The standard wireless charger uses inductive charging, which requires the phone and the charger to touch. While the phone charges, you can’t pick it up, or use it in a car or other place where your phone may shift due to vibrations. However, with the use of magnets, your phone will stay in position regardless of the conditions. There are even some magnetic chargers that allow for portable on-the-go charging, too.

    How to Choose the Right Magnetic Wireless Charger?

    We have covered many topics about wireless chargers and how to choose the right one, but let’s focus on the best features of a magnetic wireless charger.

    Securely Holds Your Phone

    Modern smartphones tend to have glass backs as its a better material for LTE signals, Wi-Fi, and Bluetooth. To use your device with a magnetic wireless charger, you need to purchase a phone case that already has metal inside of it, or a metal sticker to add to your phone or case.

    No Wireless Charging Interference

    Metals, just like magnets, can easily interfere with wireless charging. You can still position them carefully so that they do not block the phone’s wireless charging function. Some manufacturers provide magnetic wireless chargers but no matching phone cases, which means you have to find the proper accessory to make the charger work properly. A magnetic wireless charger with a matching phone case is the best option.

    A Twistable Joint Design

    A wireless charger that can be adjusted allows you to view your phone at a comfortable angle, whether you’re in the office or your car.
