One of the biggest "nightmares" of students majoring in Electricity and Telecommunications is the subject of Electromagnetic Field Theory. Many of you can write Maxwell's equations, but do not really understand why you have to study this subject. Let's refer to the following article to know more!

In the field of welding and metal processing, each welding method has its own strengths, meeting different production needs. Fish scale welding is one of the popular welding techniques thanks to its wide application, which can be applied to many types of materials from common metals to semiconductors, helping to optimize the efficiency and quality of the weld. In this article, EMIN will provide you with detailed information about fish scale welding technique and useful tips to create welds that are both aesthetic and durable.

When testing audio equipment, calibrating sensors or conducting technical research, signal generators are always the preferred tool to ensure accurate output results. In this article, EMIN will help you learn more about this device, from popular models, typical functions to the scope of application in many modern industries.

When choosing to buy equipment for measuring or repairing electricity, you may have seen the words True RMS appear on the body of the device. Devices with this feature often have a much higher price than regular models. So what is True RMS, and why is it worth it? The answer will be in the article below.

Among the current handheld angle grinders, genuine Bosch angle grinders are always the choice trusted and preferred by many users. When looking for product information, you will easily come across indicators such as 11,000 min⁻¹ or 11,000 rpm, 11,000 rpm but are not sure what they really mean? Let's find out with EMIN right away!

If you have ever used electronic measuring tools such as calipers or micrometers, you must have seen symbols such as IP54, IP65 or IP67 printed on the body of the device. For example, the Mitutoyo 293-340-30 micrometer model comes with an IP65 index. These symbols are not product codes or measurement parameters, but an important standard directly related to the durability and working ability of the device in real environments.

In strict testing environments such as oil and gas, metallurgy or aviation,... surface hardness measurement has now become mandatory standards. This is the step to verify the bearing capacity, stability and real quality of metal parts, factors that can determine the operating performance and safety of the entire system.

Starting from July 1, 2026, Hanoi's Ring Road 1 area will officially ban gasoline-powered motorbikes under the direction of the Government. This is no longer a distant vision, a specific roadmap has been planned in detail by departments and branches: from making a list of electric vehicle charging stations, supporting people to switch vehicles, to building preferential financial policies. Some locations have been proposed as parking lots combined with charging stations, such as De La Thanh Street, Kim Ma - Cau Giay area, or in front of the headquarters of Vietnam National Shipping Lines in Xa Dan - Giai Phong.
