nagsesearch ako kanina pa. nahiwagahan lang ako. report ko about inductor bukas eh. in theory, inductors are composed of coils of wire(conductor) and a core.. pero bakit po ba may magnetic wire? para mas maconcentrate ung magnetic field?  Huh

TIA  Smiley

nope. tinawag lang silang magnet wire pero enamel coated copper wires lang sila. Grin

kaya sila ang ginagamit dahil manipis lang ang coating, pwedeng heavy insulation pero manipis pa rin physically. Wink

yes enamel coated lang ito, ika nga ng
iba barnisado lang ang tawag doon.  Smiley

ahh.. i see.. tnx master rd and danny.. point for both of you..  Smiley

bakit po kelangang may ganun? para kapag may aksidenteng makahawak/maidikit dun sa coil ay hindi makukuryente or hindi makakaapekto sa circuit? wala po bang epekto un sa magnetic field na naipro2duce kahit insulated?

kaya pala parang nabalatan ko ung air-core inductor na nakuha ko sa fm/am radio namin.. barnis lang pala un.. nagtaka pa ako kung bakit infinite ung resistance nung chineck ko ng multimeter eh conductor un.. hahaha.. enamel coated wire pala kasi Grin Grin Grin

pogi ulit kasi sa akin ^_^

kaya may coating para ma-insulate 'yung turns. kung mag-short 'yung turns, lalabas wala talagang turn. Wink

kaya enamel coated instead of standard insulated wires (though pwedeng gamitin 'yun), para mas madaling magsiksik ng windings. Wink

'yung magnetic field, geometry ng construction ng inductor ang mag-dictate. tapos 'yung strength niya is proportional to NI, number of turns multiplied by the current in the inductor. made-demonstrate mo 'to sa pamamagitan ng electromagnet gamit ang Constant Voltage/Constant Current supply ng laboratory. Grin BTW, pwedeng gawin sa screwdriver 'yun, maiiwang naka-align 'yung screwdriver kaya nagiging magnet, the higher the current (or mas matagal binabad), mas malakas ang kapit.

OT: ginagawa ko 'yan dati sa gamit ng iba, lalo na sa long nose. maiinis ka kasi dumidikit sa long nose 'yung mga kinukuhang tornilyo at iba pang bakal. Grin

tnx sir rd.. gets ko na..

oo nga naman.. magdidikitdikit ung mga turns kung hindi insulated.. hahaha Cheesy Cheesy Cheesy

tnx sir RD.. hehe =)

para sa materials engineering na subject to eh.. magnetic materials ang topic ng group namin.. sa akin ung inductors.. hindi pa ako nakakagamit ng inductor aside sa step-down transformer kaya wala pa ako idea.. hehe.. tnx ulit master.. nakakainspire talaga dito sa elab  Smiley Wink Grin

pwede rin ang insulated copper wires dito basta kakasya sa space available sa yo...

Baka itanong sa iyo bakit magnetic wire ang tawag, eh di naman yung magnetized wire. Ordinary copper wire lang na may enamel coating. Wink

Manipis kasi ang insulation ng magnet wires (ferromagnetic wires are not made of copper). If insulation is thin, you have enough space for more turns that can generate more magnetic flux.
