FENOMENA ARUS EDDY PADA PLAT ALUMUNIUM MENGGUNAKAN SOLENOID BERBENTUK BALOK
Abstract: The study is to
observe the phenomenon of the eddycurrent in aluminum plate and coil shaped a
solenoidbeam has done.Eddy current phenomenon is generated in the aluminum
plate with a size of 6 x 10 cm andextended with a20 cm lenght of stick. The
source of the magnetic field is generated by a pair ofsolenoidconnected in
series and parallel combination. The solenoid was designed in from of
beamwiththe width, high, and lengthof 4,4,10 cm respectively. In order to
increment the magnetic field strength ofthe solenoids it is necessary to insert
a ferromagnetic material such as a iron into the solenoid.Aluminium plate used
was designed in four models that is with onestrip, three strips, four strips
and nostrip. The magnetic field strength is measured using Pasco PS-2162
Magnetic Probe in horizontal andvertical direction to the solenoid by varying
the distance and magnitude of applied current. The resultshow that thehighest
value of magnetic field (40.1535 mT)was produced when the solenoid
wereconnected in series connectionwith current of 7A.Eddy currents arising in
the plate is affected by themagnitude of the magnetic field strength and the
numbers of strips in the plate. The larger the magneticfield strength, the
smaller the number of oscillations. Moreover, the number of oscillation of the
plate isdecreased when the number of strips is increased. The decreasedof this
oscillation as due to the cut ofeddy current by the strips. To compare the
influence of a magnetic field strength of the oscillation of theplate, then
Neodymium Iron Boron magnets used as the source of the magnetic field and the
result showsthat oscillation was significant decreased.
