But you know its very weird. There is this impedance you writing about that is related to the change of voltage and ampere in a coil.
However this change doesn't refer to the fact that the electricity is actually charging the magnet the same way. And it is also related to AC not...
You know I dont believe in this, since the charging time must be related to the velocity of the light the coil length and some pretty complex evaluation that relates to the volume of the iron core.. As the electricity goes in it the field already exit from it and the charge propagates toward the...
Well, its like m shape and it size is like 15cm * 10cm * 15cm. Its charging less than in a 0.001 sec. I don't have better equipment to measure smaller time, so I need the calculus... The winding is on the the middle leg of the iron core.
Impedance is related to AC its a resistance type that relate to AC. Why would I even think on it?
It is a DC electro magnet:
R = 10.4 Ohm
I = 2.0 A
U = 20.8 V
By the way I know that is in the microseconds to milliseconds range
see my answer above, a DC electromagnet that has 2 amps some hundred turns and a iron core. How long does it take for the electromagnet to reach the maximum electromagnetic field strength B.
Just turn the electricity on and how long does it take to get it up and running.
Hej it doesnt matter what force is driving that mass outwards. CF or other doesn't matter! In this case the velocity that moves the object out is constant!
Anyways I found it out that in my example the results were close enough initially and later I found it out that with bigger systems it is...
I found that out that this is actually incorrect.
Just imagine a large radius disc where the two radial distance is same (on the radius)
the first pair is close to the center, the second is further.
The circum velocity of the pairs have different ratios. There the force that will accel the...
It doesnt matter that is an other example and its ok, the point is that by cross calculation you cant get it right in terms of direction but only values.
Its really getting annoying and stupid that every second thing have wrong units then we say it doesn't have units or direction that it is not...
angular velocity is not perpendicular to the rotation it is the rotation itself.
x/y plane the velocity and the angular...
Okay, so vector force = [0,1,0] vector angvel = [-50,0,0]
cross [0,1,0] [-50,0,0] = [0,0,50] that is out of the plane.
Fc = [0,v,0] × [angvel,0,0] * 2.0 * m
(min or plus depends on rot dir
okay so how is it for you that it is in plane?
So this is an official calculus
maybe you misunderstood.
Velocity dir = centrifugal force dir, object moving outward or inwards would cause the system decelerate or accelerate but the rotating frame remains the same...
In physics, the Coriolis force is an inertial force that acts on objects that are in motion relative to a...
