hi how do you calculate the turns and wire gage of a small solenoid. Say about 1/4 inch by 1/4 inch. Also I thought the more turns you put on would increase resistance which takes less current and the magnetic is not that strong. please explain. thanks
Yes it would, increasing the voltage lowers the resistance which in turn increases the current flow. it will also increase the reaction time of the electromagnet allowing it to respond much quicker to current changes.
Soft iron means it is close to pure iron which will amplify the magnetic field up to 50 thousand times as strong as air coils so your figure of x 10 is completely incorrect. also, no where does it say the wire has to be one conductor, it just says "N" number of turns. if you parallel conductors you can make a strong electromagnet with very low voltage that will be very, very strong. also wind the length of the core it's self will increase the strength considerably. as you parallel the winding's the resistance goes down as does the self inductance which makes the magnet respond very quick to current changes. this video seems to be geared towards grade school kids not adults as per the typical gibberish used. if the person does not know how to actually make an efficient electromagnet then they present it like in this video. was it helpful, well not really to an adult but to a grade school kid, maybe. he or she would get crushed in a science fair using this outline walking away with a dead last showing. of course increasing the voltage lowers the resistance which increases the current flow but then in some cases an increase in current flow is not always desirable in certain situations.
Finally someone direct in his explanation. Sub from me
this extremely helps with this last minute report i have due
Thx bro this helped
this is great and helpful.. thanks :))
Thank u sir!!

thank u
what if you increased the volt's, would this have any effect on the magnet?
8 years and still no answer.. But I also need that answer smh 😞

wow this is helpfull :D
