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.

the electromagnetic?
Answer
- Invented the electromagnetic

- William sturgeon
- Sturgeon magnet were weak, because the wire he
used could only be wrapped in a single spaced out layer around the core
- Hans in from Denmark

Active and Passive
Active
- Danish Scientist Hans Christian
Orsted was discovered in 1820 electric current that create magnetic field
- Scientist william sturgeon invented
the electromagnet in 1824
- To
insulate the winding it from vanish the iron
- His first electromagnet was about 18
turns of bare copper wire wrap iron-shaped piece
- The iron became magnetized and
attracted other pieces of iron, when the coil pass through the current.
Passive
- An electric current that magnetic an
field was discover by danish scientist hans christian orsted in 1820
- The electromagnet was invent by
scientist william in 1824
- The iron was vanished to insulate it

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.
