The science behind iPhone 12 wireless charging

Wireless charging is nothing new in the iPhone world. But the incorporation of MagPlus charging for iPhone 12 users is a quantum leap in the tech world. And Apple, as we know, always sets the bar for other smartphone brands.

So, for iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max, and iPhone 12 Mini, a magnetic attachment system is incorporated. The gadgets also feature 5G capabilities, new make-up, and the Mini goes for only $699!

The benefits of iPhone 12 wireless charging include not connecting your cable to the charger port and let us not get started on damaged ports that spell trouble! How power gets transferred wirelessly should probably inspire interest, not just for the nerd community.

How to use your iPhone 12 wireless charging model

Connect the USB-C connector on your MagSafe Charger to a suggested 20 watt (W) or more noteworthy Apple USB-C force connector or compatible third-party USB-C adapter. At the same time, you can connect it to a USB-C port on a Mac or PC. Position your MagSafe Charger face up on a level surface. Ensure that there are no metal items or other unfamiliar material nearby.


What is the science behind iPhone 12 wireless charging?

iPhone 12 wireless charging is based on the magnetism properties and their influence on other magnet-sensitive objects. To put it into perspective, a magnet flowing through a coil of wire creates a currents movement in the wire. As a result, a small light bulb is powered. 

Magnetic phone chargers pretty much work the same way, only that a few more steps are needed. Contrary to using the magnetic mechanism in controlling the coil without any physical contact, MagPlus charging uses its coil of wire. With the current flowing, a magnetic field is generated. And once current is actively passing through the coil, a second coil close by also creates current. But that is if they are close enough.

However, the current of the transmitting coil will never fall below the current of the receiving coil in short lengths. But that's not a problem you can't handle. Increasing the power and the size of the coil can help with that.

About MagSafe

MagSafe is not new in Apple; it was initially used for magnetic mechanisms while connecting a charging cable to a MacBook. And what other better time to revive it than in wireless charging? The previous models incorporated the Qi charging support of 7.5 watts, but adding the rings of magnets made the iPhone 12 series special.

For the MagSafe charger to fit perfectly, the magnets were encompassed with a charging loop in the iPhone, making it easier to adjust the coil with a supported charger. And with the higher level of 15 watts when charging, Apple gave iPhone users a run for their money. 

But that is only possible with MagPlus charging together with a power adapter of 20W or more. However, the iPhone 12 Mini can only get 12 watts at peak, unlike the other variants. 

Fortunately, any Qi charging support can go hand-in-hand with the MagSafe for users of iPhone 12 predecessors. As magnetic accessories, Apple included a wallet attachment, cases, and covers that should easily be established on the iPhone's magnetic back whenever needed.
