According to formula for the magnetic strength of a Solenoid: en.wikipedia.org/wiki/Solenoid Magnetic Field: B = μ_0*I*(N/L). Where N/L is the number of windings per meter. So according to the formula the diameter of the coil does not matter.

@@redefinitionof Thanks for looking into that. The key is the hole is filled with more windings, in fact, if the diameter does not matter, the small size in the hole is less copper for a wind. But maybe the flux loops around the outside and through the inside, so the flux must pass through the center which the iron makes happen easier. I was looking into 'coreless' motors which don't use iron. en.wikipedia.org/wiki/Electric_motor#Ironless_or_coreless_rotor_motor

It is an experimental value. It depends on your material, but also on the shape and density of the core you insert. See the link in the description.

It is in the description of the movie: M [A/m] "Magnetization"

thanks i want another thing that suppose i have to build a big magnet like core size 500x 50mm, and for the same, i am putting nos of turns is 800, then the calculation is B= Mo*H(1+x)= 4* pie*(NI/l)* 5000,where N=800,I=1.5 Amps and l= 50 MM as per calculation it is showing very less T(flux density). Can i right? if not can u shw me the exact formulla or how many turns or Amps to be taken for getting 1 T of flux induction

ple reply ase

That can be right. You are only putting in 1.5 A. That is about the maximum current from a 9V battery. If you want to be in the Tesla range, you have to use thousands of Amperes and use Superconductors. On wikipedia I read that a 13.5 T superconducting magnet uses 46 kA!!!

Magnito motive force a(actually was MMF in our time)

You don't need to measure the loaded current. Unless you don't believe in Ohm's law it is equal to the resistor voltage divided by the resistance. The internal resistance can be derived with knowledge of the open circuit voltage, loaded voltage and resistor load OR open circuit voltage, loaded voltage and loaded current. Either one is just fine.

Been a while, I did miss these replies of course. Yet I returned, once more, for nostalgia's sake. I figure it would, probably. Maybe. Maybe needs a bit more scope, another couple of maps for multiplayer or story missions for single players- and a lot of refining for an effective porting. I've refined my opinion since way back when. Success certainly does require a healthy degree of luck, but I was a high school kid when I first rambled about that and now I'm through university. So I figure a lot of it requires good intention and effective approach- and decent marketing. But the biggest part of all that is action, and the resources to maintain that sense of action mentally. You gotta make sure someone somewhere is talking about it. And if people might stop talking about it, you need to remind them by releasing information about it. Sometimes that means adding things to a game, like the big ones do- other times it just means getting someone to write an article about it. Or engaging in a social media structure surrounding it- updating a twitter or a facebook or something that people maintain vague awareness of. It requires effort. And 'luck', but these days I figure that has more to do with **audience**. What do people want? What do they look for? That's what Pewdiepie did right, that's what Angry Birds did right. Apparently geeks like me loved Reactive. It was like... Unreal Tournament, or something. Organic. So effectively what I said 8 years ago, just longer-put. Luck just means community. It's gotta be able to spread. Like a big nasty pandemic or something. >>

I guess a big part of it is marketing. Because after so long, I'm still here thinking about it- but when I bring it up to anyone, nobody ever knew about it. But it always pops back into my mind. So very novel. It popped back in my mind recently because two games using a similar sort of paper doll-esque physics setup are doing decently well. Thriller games- Hidden Deep and Barotrauma. Made me think of these lovely little lizard dudes again. So it was certainly memorable, at least for me. Just unheard of by the rapidly changing sense of mainstream appreciation. .... Like the boss fight. I recall a fun boss fight. ....

Yes, it might have been just over the horizon. The doll movement was actually an attempted shortcut, because I did not want to animate movements and the physics engine was in place. In the end I think animating was actually less work.

@@redefinitionof Ended up looking pretty charming, all things considered =)

when you create a new region, the tile sizes are randomized. find a big one and build the city on there.
