磁铁真的会毁了你的智能手机吗?

Do magnets actually pose a terrifying risk to ourgadgets, and where did we get the idea that they’redangerous in the first place?

磁铁真的会对我们的智能工具造成威胁吗?我们又是为什么会认为它们是危险的?

Let’s find out.

现在我们就来揭晓答案。

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, "Whenplacing a strong magnet near one of these you could distort the picture. Thankfully, moderntelevisions and monitors aren’t susceptible in this way."

“老式电子设备如 CRT 显示器和电视机易受磁场影响，first4magnets公司的马特·纽比解释道，“当你在这些设备附件放置强力磁铁时，画面可能会变形。不过值得庆幸的是，现代电视机和显示器不易受到此种影响。

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

大多数现代电子产品，比如我们的智能手机，不太会受到小型磁铁的不利影响，不过事情真是如此吗?

How do magnets affect smartphones?

磁铁是如何影响智能手机的?

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, "Infact, within the device there will be a number of very small magnets which perform importantfunctions.For example, the new Apple Watch uses a magnetic inductive wireless chargingsystem."

马特表示“我们在日常生活中见到的绝大多数的磁铁，甚至市面上那种超强磁铁都不会对指智能手机造成伤害，“事实上，在一些装置内会有若干非常小但却发挥重要作用的磁铁。例如，最新一代的苹果手表就使用了磁性感应无线充电系统。

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

不过，在你大松一口气，开始用磁铁在你的智能手机上划来划去之前，还要了解一些事情。

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

马特警告说，磁场可能暂时干扰智能手机里的数字罗盘和磁强计，而其后果远比你想象的严重。

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

其实，K&J Magnetics工程师已经用iPhone进行了实验，来检测磁铁会如何影响iPhone内部的传感器。

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

“我们发现附近的磁铁会影响手机内部的磁性传感器。造成指南针失常，K&J Magnetics的工程师Michael Paul解释道，“更糟糕的如果你在手机旁放置强力磁铁，里面的一些钢构件会稍稍磁化，他们会变成弱磁铁。这样指南针便难以正确校对。

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

你可能认为这不重要，因为你从来不使用指南针这个应用程序，但这并不意味着其他应用程序不依赖于相同的传感器。

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

例如，谷歌公司(GOOGLTech30)的谷歌地图就使用传感器来检测你的朝向，而且很多游戏也依靠它来判断你的方向。

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

虽然磁铁不会让你的智能手机报废，但它极有可能扰乱一些重要的原件，因此我们完全不必冒这样的险。
