NICE ! One mistake in my previous post by the way, its not a steel core , its an iron core. Well, got to go to the hardware store now ... And I would take full notice of safety issues, thanks for reminding me !

Thanks a lot guys. That was the support I guess I needed. Well I did all the math, I would post it for maybe anyone of you to check it, the force I calculated was around 4300 Newtons. But I made an assumption of B=1.2T with Ur(mu R) being 3000. A query if you might help me with, in the...

Firstly its a hobby thing. Secondly, I have got a design, you just do not go by opposing the design and present a whole new mechanism, you provide small alterations to the design. All I wanted was how to construct an electromagnet that could lift 600lbs with 24/12Volts power supply. Building...

Then do not take a quick look please . this is the forums , you have to help others, give time to them , come on , this is not fair. Berkeman, help please ... This is a burning issue on forums, not a single forum on the internet deals with designing the electromagnet properly, you have to...

Well I have got a lot of text warnings. Sorry for my disrespectful attitude Sir. My request to you is just to look at the following link and explain the structure and design. It would be very thankful,grateful,utmost kind of you...

close this thread because i aint comin back

berkman ... I am a newbie . ... let's face it ... i don't have answers to ur so called 'quiz questions', rather dealing me with sarcasm you could have some positive attitude and help me. I am in my 5th semester here, not working for a company like you. I just asked you to help me make a...

cmon dude ... don't be that harsh ... I've read your post again ... look yours idea changes my design. I am not making a mechanical lock, its a MAGNETIC LOCK. My design is similar to those that are out there in the market. I gave the link too. I mean guys making those kinda locks aint fooling...

bro ... if you're wondering the 'behind the door' buttons to malfunction, just pull the plug out and the doors open ... i hate quizzes though .. aint that sharp ...

well kind of .. like i said , there are going to be two button behind the door, one for lock and the other for unlock. You can have a knob to pull the door open ...

eerrr ... you talk about fire codes ... we don't have fire alarms here ...

great ideas there ! why i was designing for continuous power ? Because this lock is for home use where you have to lock the door usually at night but perhaps i might want to rethink it. Another reason is that i saw these magnetic locks on the internet and they work the same way. Check the...

eeeh ... i don't know who's ugly question was i answering ... i read the post again .. u guys were just refuting skeptics idea... :confused:

OK guys ... i better tell ye all abt the whole project because u guys r makin fairy tails. The project consists of a keypad, lcd and a lock. The key pad and lcd would be in front of the door. The door can be unlocked from the front by only entering the correct password. There is going to be a...

like ur style bro ... but I am in the south asia ... so might want to re-think my opportunities here ... i thought i would give it a go myself, make one of those but turns out it aint easy , lots of calculations involved. Would be helpful if you guide me through the design procedure ... like...
