The Twelfth Meeting

Date: 29 December 2017

Assalamu'alaikum Wr.Wb

Hello Friends

This Friday is the last day of the presentation. Today the preliminary will be the sixth group, the sixth group being postponed two weeks ago. Before the presentation I spoke to Ms.Rella, I asked "should I join their group?". Because my group has no news in the past few weeks. Ms.Rella agreed and I immediately joined and started her Presentation. When finished Ms.Rella sees and corrects what we present, I said very well the presentation of this group. Only Ms.Rella said explanation of 5W1H and Active / Passive less much. Once it is done we all close the presentation and return to their respective places.

Electromagnet   (Article)                              

Danish Scientist Hans christian orsed discovered in 1820 that electric currents create magnetic fields. Scientist william sturgeon invented the electromagnet in 1824.His first electromagnet was a-shaped piece of iron that was wrapped with about 18 turns of bare copper wire (insulated wire didn't exist yet). The iron was vanished to insulate it from the windings. When a current was passed through the coil, the iron became magnetized and attracted other pieces of iron; when the current was stopped, it lost magnetization. Sturgeon displayed its power by showing that although it only weighed seven ounces (roughly 200 grams), it could lift nine pounds (roughly 4 kilos) when the current of a single-cell battery was applied. However, sturgeon's magnets were weak because the wire he used could only be wrapped in a single spaced out layer around the core, limiting the number of turns.

Beginning in 1830, us Scientist Joseph henry systematically improved and popularized the electromagnet. By using wire insulated by silk thread, and inspired by schweigger’s use of multiple turns of wire to make a galvanometer, he was creating powerful magnets with thousands of turns of wire, including one that could support 2,063 1b (936 kg). The first major use for electromagnets was in telegraph sounders.

TRANSLATE

Ilmuwan Denmark Hans Christian ørsted ditemukan di 1820 bahwa arus listrik membuat Medan magnet. ilmuwan William Sturgeon menemukan elektromagnet di 1824.pertama elektromagnet adalah berbentuk potongan besi yang dibungkus dengan sekitar 18 putaran telanjang kawat tembaga (kawat berisolasi tidak ada belum). besi itu dilennyapkan untuk melindungi itu dari gulungan. ketika arus melewati coil, besi menjadi magnet dan menarik lainnya potongan besi; ketika saat ini dihentikan, kehilangan magnetisasi. Sturgeon ditampilkan kekuatannya dengan menunjukkan bahwa Meskipun hanya ditimbang tujuh ons (kira-kira 200 gram), itu bisa mengangkat sembilan pound (kira-kira 4 kg) ketika arus satu-sel baterai diterapkan. Namun, Sturgeon dunia magnet yang lemah karena  kawat ia digunakan hanya bisa dibungkus dalam satu spasi lapisan sekitar inti, membatasi jumlah berubah. mulai tahun 1830, kami ilmuwan Joseph Henry sistematis membaik dan mempopulerkan elektromagnet. menggunakan kawat terisolasi dengan benang Sutera, dan terinspirasi oleh schweigger penggunaan beberapa putaran kawat untuk membuat galvanometer, ia mampu, menciptakan kuat magnet dengan ribuan berubah dari kawat, termasuk salah satu yang bisa mendukung 2,063 lb (936 kg). Penggunaan utama pertama untuk elektromagnet adalah suara telegraf.

Maybe that's just the story of today, Thanks for attention.
