A transformer is a device that is built based on the principle of mutual inductance and can be used to increase or decrease the voltage or current, and transfer electric energy from one circuit to another. It also can be used for impedance matching. Transformers have a very wide range of applications in power systems, tele communications, radio, instrumentation and many other electrical and electronics fields.","PeriodicalId":183799,"journal":{"name":"Understandable Electric Circuits: Key concepts","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114568137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This phenomenon has industrial, biological and physiological importance. In chemical process engineering, it is encountered in both separ- ation processes and reaction engineering. In some cases, a chemical reaction may deliberately be employed for speeding up the rate of mass transfer and/or for increasing the capacity of the solvent; in other cases the multiphase reaction system is a part of the process with the specific aim of product formation. Finally, in some cases, for instance \"distillation with chemical reaction\", both objectives are involved. Although the subject is clearly a chemical engineering undertakin~, it requires often a good understanding of other subjects, such as chemistry and fluid mechanics etc., leading to publications in diversified areas. On the other har.d, the subject has always been a major field and one of the most fruitful for chemical engineers.","PeriodicalId":183799,"journal":{"name":"Understandable Electric Circuits: Key concepts","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121430313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Permanent magnet is a magnet that retains its magnetism over a long period of time after it is removed from a magnetic field. Magnetism is the attraction or repulsion properties of a magnet. A magnet has two areas of strongest force, called poles. Every magnet has a North and South Pole (N and S). The basic law of magnet: Like poles repel, unlike poles attract. Magnetic field is a place near a magnet or a moving electric charge where magnetic properties are produced (an invisible area of magnetism produced by moving the electric charge). Electromagnetic force is a force between charged objects around their electric and magnetic fields. Magnetic field lines (the lines of force) around a magnet describe the directions of the magnetic field (they can be plotted with iron filings and paper). Outside: the magnetic field lines travel from the North Pole (N) to the South Pole (S). Inside: from the South Pole to the North Pole.","PeriodicalId":183799,"journal":{"name":"Understandable Electric Circuits: Key concepts","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129679037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
