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.

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.
