What is Electromagnetism ?

Electromagnetism

This year, researchers have devised a new version of the field that can be used to make chips more energy efficient.

Before we explain how, let’s consider the hot metal. This is how it works:

To make electrons flow through a metal, you need to apply an electric current.

This can happen either through an electric field—when you put some metal into an electric field and watch it draw current—or with an electrical current passing through a metal—which is what happens in a computer, but in reverse.

For some metals, you can make it flow through an electric field using an iron or a copper wire.

Some other metals, you can make it flow through a current passing through the metal—like how you have a transistor.

But the problem is that they both have the same problem: they slow down the electrons. The more magnets you add, the less resistance the wire will have to have.

This can slow down the electrons so much, they have to spend most of their time getting rid of energy as heat.

A bigger problem is that, because the electrons get stuck on the surface of the metal, they can’t flow through the metal as easily as they do in the wire version. This means you need more magnets.

The perfect setup, because it has much higher resistance, is to apply a current passing through a magnet. This means you don’t need as many magnets, so you don’t need as much heat.

The problem is, not all magnets can be electrified, which is what lets us use this technology.

To fix this, you make it work by controlling the temperature.

The problem is, the current through the magnet is so small, it has no effect.

To solve this, you add another metal to act as a heat sink.

This gives the electrons somewhere to go to get rid of their heat.

At this point, they’re back to being electric and not magnetic, so they can flow through the metal.

This metal is a semiconductor.

You can find one in the form of silicon. It’s much easier to control.

So you stick the semiconductor on the side of the magnet, make the magnet bigger, and your device has magnetoelectric coupling.

Which is how it works.

Transistors

This year, we saw a few new breakthroughs in computers.

Most notably, we have seen a fundamental breakthrough that allows us to make transistors smaller.

It’s called vertical scaling, and it involves wrapping a piece of silicon around another piece of silicon to make smaller transistors.

Of course, if you want them smaller than 1nm, you need to make them smaller than they can possibly be.

This year, they did.

They just got that little bit smaller.

But they’re still only 10nm.

While they’re still a couple of years away from reaching the bigger scale, this was an incredible achievement for the semiconductor industry.

We’re getting closer to making transistors cheaper and more efficient, and a lot of the semiconductor industry hopes that this technology will also help them make smaller, cheaper, and more efficient CPUs.

Self-Driving Cars

2017 was the year that truly major companies started investing in self-driving car technology.

GM, Uber, and Volvo all announced that they’ll be making cars that drive themselves, and we now have prototype systems that can drive themselves without the help of a human driver.

While a few companies like Google are working on this, a lot of major companies are rushing to try and get in on the market.

This means self-driving cars are soon going to be more common than they already are.

Wireless Charging

We saw something really big this year: wireless charging systems coming from almost every major smartphone company.

Apple was first out the gate.

Apple announced the iPhone 8 and iPhone 8 Plus and made them work on their wireless charging mat.

This mat will be called AirPower, but Apple hasn’t revealed the charging mat’s charging rate. It’s possible that it will charge your iPhone, Apple Watch, and AirPods all at once, but Apple hasn’t said anything yet.

Meanwhile, all the Samsung Galaxy devices, all the Google Pixels, and all the HTC U11s have Qi-compatible charging ports.

The rumors are all that we’ve got about the LG V30’s wireless charging, but it sounds like it’s also going to charge up your phone quickly.

We’re also expecting to see wireless charging coming to Samsung’s laptops this year, as well as lots of laptops from other manufacturers.

While that may not sound like a lot at first, it is important. If all the laptops are using wireless charging, then you won’t need to plug in your laptop’s charger whenever you need to charge your device.

Bigger, better TV

2017 saw the release of some really, really big televisions.

As a reminder, a TV is a computer with a screen. So every year, televisions get bigger and bigger and more powerful.

The LG Signature OLED TV W looks like it’ll be the biggest TV of 2017.

This TV has a screen that measures almost 93-inches.

The LG Signature OLED TV W is so big, that if you have the room, it might
