磁鐵真的會毀了你的智能手機嗎?

Do magnets actually pose a terrifying risk to our gadgets, and where did we get the idea that they’re dangerous in the first place?

磁鐵真的會對我們的智能工具造成威脅嗎？我們又是爲什麼會認爲它們是危險的？

Let’s find out.

現在我們就來揭曉答案。

This more than likely stems from old electronic devices, such as CRT monitors and televisions, which were susceptible to magnetic fields, explains Matt Newby from first4magnets, "When placing a strong magnet near one of these you could distort the picture. Thankfully, modern televisions and monitors aren’t susceptible in this way."

“老式電子設備如 CRT 顯示器和電視機易受磁場影響，”first4magnets公司的馬特·紐比解釋道，“當你在這些設備附件放置強力磁鐵時，畫面可能會變形。不過值得慶幸的是，現代電視機和顯示器不易受到此種影響。”

Most modern electronics, like our smartphones, are not going to be adversely affected by small magnets; but is that all there is to it?

大多數現代電子產品，比如我們的智能手機，不太會受到小型磁鐵的不利影響，不過事情真是如此嗎？

How do magnets affect smartphones?

磁鐵是如何影響智能手機的？

The vast majority of magnets that you come across day to day, even many of the super-strong ones on the market, will have no adverse effect on your smartphone, says Matt, "In fact, within the device there will be a number of very small magnets which perform important example, the new Apple Watch uses a magnetic inductive wireless charging system."

馬特表示“我們在日常生活中見到的絕大多數的磁鐵，甚至市面上那種超強磁鐵都不會對指智能手機造成傷害”，“事實上，在一些裝置內會有若干非常小但卻發揮重要作用的磁鐵。例如，最新一代的蘋果手錶就使用了磁性感應無線充電系統。”

However, before you get carried away and start rubbing magnets all over your smartphone, there is something else to consider.

不過，在你大鬆一口氣，開始用磁鐵在你的智能手機上劃來劃去之前，還要了解一些事情。

Matt warned that magnetic fields can temporarily interfere with the digital compass and magnetometer inside your smartphone, and that’s more serious than you may think.

馬特警告說，磁場可能暫時干擾智能手機裏的數字羅盤和磁強計，而其後果遠比你想象的嚴重。

The engineers over at K&J Magnetics actually experimented with an iPhone to show how the sensors inside can be affected by a magnet.

其實，K&J Magnetics工程師已經用iPhone進行了實驗，來檢測磁鐵會如何影響iPhone內部的傳感器。

The problem we found is that a nearby magnet will affect the internal magnetic sensors inside the phone. The compass won’t read correctly, explained Michael Paul, an engineer at K&J, "What’s worse, if you stick a strong magnet to the phone, you could slightly magnetize some steel components inside, making them act like weak magnets. This can make it difficult to properly calibrate the compass."

“我們發現附近的磁鐵會影響手機內部的磁性傳感器。造成指南針失常，”K&J Magnetics的工程師Michael Paul解釋道，“更糟糕的如果你在手機旁放置強力磁鐵，裏面的一些鋼構件會稍稍磁化，他們會變成弱磁鐵。這樣指南針便難以正確校對。”

You might think it’s unimportant because you never use the compass app, but that doesn’t mean other apps aren’t relying on the same sensor.

你可能認爲這不重要，因爲你從來不使用指南針這個應用程序，但這並不意味着其他應用程序不依賴於相同的傳感器。

Google (GOOGL, Tech30) Maps, for example, uses the sensor to detect which way the phone is facing, and a number of games also rely on it to work out your orientation.

例如，谷歌公司（GOOGLTech30）的谷歌地圖就使用傳感器來檢測你的朝向，而且很多遊戲也依靠它來判斷你的方向。

It seems as though magnets aren’t likely to kill your smartphone, but there’s definitely a possibility they’ll mess some pretty important aspects up, so why take the risk?

雖然磁鐵不會讓你的智能手機報廢，但它極有可能擾亂一些重要的原件，因此我們完全不必冒這樣的險。
