Electricity and magnetism.

“What you need to know is that any object with the power of energy potentially also has a magnetic field.”

For example, a light bulb shines but you cannot sell the magnetic field it gives off: that light bulb only exists because the current flows through the wiring, hence the magnetic field.

Magnetism and electricity are two sides of the same coin. When there is electricity it flows through the magnetic field.

The more wire there is, the stronger the magnetic field. In fact, to produce a strong magnetic field takes a lot of copper.

Copper also protects electrical technology from excessive electromagnetic waves such as radio frequencies. It is corrosion-resistant and reduces deterioration. It is durable and is the best conductor of energy there is.

But, wireless charging technology hasn’t changed much since Tesla’s discovery. He is the one who realized its double potential. But no one could find an appropriate use.

Most mobile devices today have an electromagnetic coil attached to their hardware.

A very similar and more powerful coil is inside the charger. With electricity, the coil becomes a source of the electromagnetic field.

When the latter encounters the coil located in the telephone, they interact with each other. As if they were two brothers, one older and the other younger. And the larger field supplies electricity to the smaller one.

Here’s how wireless charging works, using the same principle the phone or laptop can charge even if they are not connected.

HOW WIRELESS CHARGERS ARE MADE

To date, the challenge for engineers is to make the chargers super-efficient. That is, make them so they can exchange electricity as if there were a cable connected. Maybe even to do it remotely.

Let me explain:

At the moment the energy and the electromagnetic field do not pass from one side to the other with efficiency. I must admit that the classic battery charger with the wire is even faster than an electromagnetic field.

“Wireless charging takes twice as long. Even then the devices have to be close to each other to transmit the necessary energy. ”

For example, wireless devices are made like mats. So that you can keep the phone on it because there is a need for contact.

I must say they are well built and blend in with the many objects that a person can have on their desk.

There is no breaking of a battery charger cable box. They are not large or bulky.

You can put your phone off and on the charge in a snap if you need to make a phone call.

In short, they are very convenient but still far from mass production. At the moment they are not as fast as charging with the cable. It’s called wireless but it’s really not because the smartphone must be in contact.
