Many new computers are only equipped with a USB-C interface. Although it is a future trend, it is inconvenient for the user's use. After all, people will not throw away the standard USB device.
Many people don't buy a 12-inch MacBook or a new MacBook Pro because of interface problems. Yes, I can't imagine that I need a converter when I use my laptop to charge the iPhone 7 Plus. I can only say that this experience is not what I want.
However, Apple doesn't seem to mind, because there are still many users who will buy new MacBooks and converters. Of course, this idea has also been recognized by some commentators and the media.
For example, Thenextweb believes that USB-C is actually the best computer interface ever. The reason is simple: it's as small as a micro USB, plugged in anyway, can transfer audio for fast charging, and is fully inclusive and integrates Thunderbolt 3 compatibility for up to 40 Gbps of data throughput.
Best of all, you don't have to think about it. The USB-C interface plugs in and can be plugged into the computer. After a while, you will fall in love with it.
Of course, USB-C is currently facing "growth troubles" because it is not popular, so adapters are necessary. For example, if you are an iPhone user, you need to purchase a USB-C to Lightning. If it is an Android user (the phone is a micro USB), you also need a converter. Most importantly, many computers are only equipped with a USB-C (such as a 12-inch MacBook), then you must buy a Hub, otherwise the U disk will not be used when the notebook is charging.
Buying a variety of USB-C adapters is also a small expense
On the positive side, USB-C can replace a variety of interfaces, such as 3.5mm, USB-A/B, micro USB, HDMI or Mini DisplayPort, as long as all computers and accessories manufacturers agree, only use USB- C standard, this is undoubtedly a long process.
Isotropic magnets are magnets with a random direction of magnetization in the magnet.
Magnet powders for isotropic magnets contain crystals in one magnet particle with a direction of random magnetization, and cannot be made anisotropic magnets when a magnetic field is applied externally during molding. In the magnetization after molding, the magnetization of the same component as the direction of the magnetization field becomes strong for the magnetization in a random direction in the crystal. Therefore, the molded body, which is an aggregate of crystals, can be a magnet having a magnetic force in the direction of magnetization
