Induction of what? I have no idea what that graph represents. Please present the entire question with all needed background info.totalnewbie said:What is the induction at infinity ?

I had a solenoid and its length was 0,222 meters. The diameter of the solenoid was 120 mm.Doc Al said:Are you asking about the magnetic field outside of a solenoid as distance goes to infinity?
What formula did you use? What does that graph represent?
That's not much of a solenoid--generally solenoids have a length much greater than the diameter, assuring a relatively homogenous field inside the solenoid.totalnewbie said:I had a solenoid and its length was 0,222 meters. The diameter of the solenoid was 120 mm.
Your solenoid is only 22.2 cm long--moving 12 cm from the center takes you outside the coil!My goal was to measure the magnetic induction of the solenoid at solenoid axis. The current that runs through solenoid is a sinusoidal AC.
The coil was used to measure magnetic induction. At the axis
the voltmeter shows me that at the center of solenoid the voltage is about 0,40 Voltage. Moving away from the point at center reduces the voltages. In other words about 12 cm away from the center shows me that the voltage is 0,18 V. Why does moving away from the center point at solenoid reduces voltages ?
The magnetic field is homogenous inside a solenoid--that's not what you have here. You need to be away from the edges, for one thing. Take a look at the http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/solenoid.html" --your setup is partway between loop and solenoid.The formula for calculating magnetic induction at certain distances from the center point was:
induction = (l/2 - x)/sqare root((l-2x)^2+D^2) + (l/2 + x)/sqare root((l+2x)^2+D^2) where l is length of solenoid and D is diameter of solenoid.
The condition l >> D is not satisfied.
I was told that magentic field was homogenous. Why does the voltages reduces if magnetic field is homogenous ?
Induction at infinity is a concept in electromagnetism that refers to the strength of an induced electric field at a point that is infinitely far away from the source of the field.
The induction at infinity can be calculated using the principle of superposition, where the electric field at infinity is the sum of the electric fields from all the charges in the system.
Induction at infinity helps us understand the behavior of electric fields in an infinite system, and is used in calculations for various applications, such as determining the potential energy of a charge distribution.
No, induction at infinity is only present in electric fields that are created by a continuous charge distribution, such as in a wire or a sheet of charge. In point charge systems, the induction at infinity is zero.
Yes, the induction at infinity can be negative if the net electric field at infinity is directed towards the source of the field. This means that the induced electric field at infinity is acting in the opposite direction of the original electric field.
