TUGAS KEPUSTAKAAN KIMIA
MAGNET
A. Pengertian/
konsep
·
“It’s said to have a
permanent magnetization and is called a permanent magnet.”(Roald K , 1979
: 352 )
·
“Faraday mengemukakan
konsep-konsep tentang garis gaya serta medan magnet dan listrik.” ( John
Gribbin, 2003 : 9 )
·
“A compass needle
points north because the earth itsself is a magnet.” (Hagh D.
Young, 2007 : 658 )
B. Bagian
magnet
·
“The region was then
known as magnesia and the ore was called magnetite. Piece of magnetite are
known as natural magnet.”( John E.William, 1981 : 465 )
·
“In what are called
hard magnetic materials, domains remain aligned even after the external field
is removed, the result is a permanent magnet.”( Chris Vuille, 2009 : 651 )
C. Kegunaan
·
“The magnet is used to
focus positron on to sample which is ussually kept at liquid temperatures.”(
Brian William, 1977 : 277 )
·
“Magnets are used in such devices as meters, motors and loudspeakers.”(
Chris Vuille, 2009 : 626 )
·
“Magnets have been used
for navigation at least since the 11th century. Magnets of this short are
called permanent magnets.”( Hagh D. Young, 2007 : 650 )
·
“In a particular, an
infinitesimal permanent magnet itself produces a dipole field.”( P.C.
Clemmow, 1973 : 162 )
·
“These alloys make very
good permanent magnets.”( George R. Tracy, 1983 : 518 )
·
“These
metals make good temporary megnets and are used as cores for electromagnetics.”(George
R. Tracy, 1983 : 518 )
D. Pembuatan
magnet
· “Making
a permanent magnet.”( Walter R. Brown, 1972 : 264 )
·
“Pick up a pin with the
ends of your horseshoe magnet and notice
that the spin is attracted to both ends of the magnet.”( Walter R. Brown,
1972 : 265 )
·
“But the hardest
materials are sought for making efficient permanent magnet.” (P.C.
clemmow, 1973 : 160 )
·
“Imagine first a
permanent magnet in the form of a thin torus.” (P.C. clemmow, 1973 : 160 )
·
“Some materials have
the properly that even in the absence of a B field, the permanent dipoles are
at least partially aligned and the material is said to be permanently magnetized
or to be a permanent magnet.”( Roald K, 1979 : 387 )
·
“As a third example,
take a bar magnet assembled from a large number of molecule dipole.”(
D.F Lawden, 2005 : 26 )
·
“Some ferromagnetic
materials retain their magnetization even after the external magnetic field is
removed. These materials can thus become permanent magnets.”(
Hagh D. Young, 2007 : 661 )
