COIL

06/23/2010 7:59 PM

Hi,

I have to make a coil and the B I need is 35000nT, air core ,right now using 320 turns in two layers turns and L(linear length of solenoid)=0.045m

I am not getting Desired B.

Please help me how would i get B=35000nT.

Since the solenoid is short and closer to a single turn geometry, the coil radius will be an important factor. This link should be more useful...
