ABSTRAKPada laporan akhir tesis ini telah dikembangkan suatu sistem untuk magnetisasi
bahan magnet menjadi magnet permanen dan demagnetisasi dengan
mengurangi kuat medan magnet suatu magnet permanen. Sistem ini digunakan
untuk magnetisasi bahan magnet seperti Ferit, PrFeB, NdFeB dan jenis
bahan magnet yang lain. Bahan magnet dapat dimagnetisasi menjadi magnet
permanen dengan menerapkan medan magnet sampai diatas titik saturasi
magnet dari bahan magnet pada waktu singkat atau dikenal dengan impulse
magnetizer. Penerapan medan magnet menghasilkan momen magnetik dan
memaksa domain-domain magnetik secara bertahap mengikuti arah medan
magnet yang diterapkan. Jika medan magnet eksternal lebih kuat dari medan
magnet saturasi magnetik dari bahan magnet maka domain-domain magnetik
akan diorientasikan dengan arah yang baru. Sistem ini menggunakan kapasitor
untuk menyimpan muatan listrik dan kemudian diterapkan pada lilitan
kawat berbentuk solenoid multi lapis. Pada tesis ini telah berhasil melakukan
magnetisasi dan demagnetisasi bahan magnet Ferit, PrFeB dan NdFeB dengan
ukuran bahan maksimal 26mm.
ABSTRACTOn this nal thesis report has been developed a system for the magnetization
of the magnetic material become permanent magnets and demagnetization
by reducing the magnetic eld strength of a permanent magnet. This system
is used for magnetize the magnetic material such as Ferrite, PrFeB, NdFeB
magnets and other types of magnetic materials. Magnetic material can be
magnetized into a permanent magnet by applying a magnetic eld above the
saturation point of the magnetic material in a short time, known as impulse
magnetizer. Application of a magnetic eld generates a magnetic moment and
domain-domain magnetic force gradually follow the direction of the applied
magnetic eld. If the external magnetic eld is stronger than the magnetic
eld of a magnetic saturation of the magnetic material, the magnetic domains
will be oriented to the new direction. This system uses a capacitor to store
electrical charge and then applied to the multi-layer solenoid or coil by discharging
process. On this thesis has been successfully doing magnetization
and demagnetization magnetic materials such as Ferrite, NdFeB, PrFeB with
a maximum material size of 26mm.;On this nal thesis report has been developed a system for the magnetization
