We replied fourth group, miss. Group of four forward and start introducing self one by one, I am a member of group of four. Member of group four, there me Muhamad Azis Rizal Rifa’I, Adianto, Fajar Ardiansyah, Muhamad Fachri dan Alif Bagaskara. One of our member there who can not attend that is Muhamad Fachri. And than which become moderator is Fajar Ardiansyah. After complete of introducing by self, we went straight in to the topic of discussion that is about “The Use Of Electromagnet”. First discusses the article. Second discusses question 5W + 1H. Third discusses verbal and nominal sentence. Fourth discusses tenses, its patern and reason. Fifth discusses active and passive sentence. And the last discusses translation from article under discussion. when finish presenting, group of four asked the audience, does anyone want to ask? there are some who ask and group of four can answer the question. After finish of question and answer session, The lecturer correcting result the presentation from the first discusses article until the last discusses translation.

The use of Electromagnet

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnetic has created by way of wrapping the wire on a conductor metal such as iron or steel, then irrigated with an electric current, and change the iron or steel inside the coils into a magnet.

Danish scientist Hans Christian Orsted had discovered in 1820 that electric currents create magnetic fields. British scientist William Sturgeon had invited the electromagnet in 1824. Begining in 1830, US scientist Joseph henry systematically had improved and popularized the electromagnet.

This is example for application electromagnetic on daily life :

Electric bell

An electric bell is a mechanical bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing or clanging sound. Electric bells have been widely used at railroad crossings, in telephones, school bells, and doorbells.

Kegunaan Elektromagnet

Elektromagnet adalah sebuah tipe magnet dimana medan magnet dihasilkan dari sebuah arus listrik. Medan magnet menghilang saat arus listrik dimatikan. Elektromagnet dibuat dari lilitan kawat pada logam konduktor seperti besi atau baja, kemudian dialiri dengan arus listrik, dan mengubah besi atau baja didalam didalam kumparan magnet.

beberapa sejarah ilmuwan elektromagnet      

ilmuwan Denmark Hans Christian Orsted menemukan bahwa arus listrik membuat medan magnet pada tahun 1820. Ilmuwan Inggris William turgeon menemukan elektromagnet pada 1824. Dimulai pada 1830, ilmuwan Amerika Joseph Henry secara sistem sudah meningkatkan dan mempopulerkan elektromagnet. 

Berikut contoh pengaplikasian elektromagnet di kehidupan sehari hari :

u  Bel listrik

Bel listrik adalah sebuah bel mekanik yang fungsinya dari sebuah elektromagnet. Ketika arus listrik dialirkan, maka ia menghasilkan suara dengungan berulang atau suara berdering. Bel listrik secara luas digunakan pada palang kereta api, telepon, bel sekolah, dan bel pintu.
