density can only exist in two or three dimensional space no?!?
we can have 100 ampere turns in one cubic meter, but in a dimensionless meter??
you say dimensions are irrelevant, but i can not see how you can have density without dimensions...
thank you that made it a little bit clearer, but a solenoid has length width height and copper winding length. does m in (A/m) refer to the length of the copper wire?
hello,
I can't seem to make sense out of amper/meter...one amp flowing throw a wire with a length of 0.5m would be 2A/m ? how does relate to the magnetic field?
So I am trying to come up with a magnet parts lifting device that can be temporarily turned off
Their theory was, take two magnets (7x7x1.5mm in this case) place them between two iron plates with opposing poles and there should not be any field lines leaving the iron.
Take away one of the...
according too: http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/wirfor.html#c1F=(u * I *I2)/(2pi *r )
i thought it would be inverse proportional to the square of the distance?! can this be right?
ok looking at datasheets for mostfet there is source/drain rise and fall time. does this only depend on the voltage rise fall time of the gate?
so if you apply a voltage to the gate it will take a wile until the voltage of the actual gate reaches that of the applied voltage because of...
is it possible to make a cold (room temp) charged gas?
would be nifty to use in a heat pump. instead of using compressors you could use fields to compress and decompress the gas
thats not true
for +-intergers
random+random!=0
if you have an infinitily large statisical sample it tends to be might be 0 (not sure if that's true for all cases)
then again the vibration is not random it just apreas that way because if you have a large sample.
yeah hence you need a temp...
torque is mesured in Nm (i hope at least, if not google tourque unit converstion). that means that if you push with a force of 1N on a lever of 1m you have a tourque of 1Nm
if you want to push your bike with a force of 1N and you tire radius is 1m you need a tourque of 1Nm on the tire. if you...
