(Summary description)Ampere's rule:

Ampere’s law, also called the right-hand spiral law, is a law that expresses the relationship between the current and the direction of the magnetic field of force excited by the current

(1) Ampere's rule in the energized straight wire (Ampere's rule 1): Hold the energized straight wire with your right hand, let your thumb point to the direction of the current, and four fingers point to the direction of the magnetic force around the energized straight wire.

(2) Ampere's rule in energized solenoid (Ampere's rule two): Hold the energized solenoid with your right hand, make the four fingers bend in the same direction as the current, then the end pointed by the thumb is the energized solenoid N pole

Nature

The ampere rule of linear current is also applicable to a small section of linear current. The ring current can be regarded as composed of many small segments of linear current. For each segment of linear current, the ampere law of the linear current is used to determine the direction of the magnetic induction intensity on the central axis of the ring current. Superimposed to get the direction of the magnetic line of induction on the central axis of the toroidal current. The ampere law of linear current is basic, and the ampere law of circular current can be derived from the ampere law of linear current. The ampere law of linear current is also applicable to the magnetic field generated by the linear movement of electric charge. At this time, the direction of current is the same as that of positive charge. Same, opposite to the direction of negative charge movement.

Advantages of electromagnetic heater

With the development of industry, electromagnetic heating storms have swept across. Electromagnetic heaters are not only used in industrial fields, but also integrated into heating and bath heating in our lives. So is the electromagnetic heater really that good?

The technology and application of electromagnet

The technology and application of electromagnets are divided into the following points 1. The position of electromagnet in the industry is very important. It is a basic electrical appliance and is known as the "king of electrical appliances". With the continuous development of the magnet and iron removal equipment market and the intensified competition, users not only have higher requirements for the quality of electromagnets and iron removal equipment, but also have higher requirements for production efficiency. In order to improve the quality and production efficiency of electromagnets and iron removal equipment, enrich my country's product categories, enhance industry product awareness, promote the development of China's electromagnet and iron removal equipment industry, and promote the research and application of electromagnet and iron removal equipment technology at home and abroad, organize Some activities.
