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.
