Inductance Definition and 460 Threads

Inductance Measurement of a Pulsed Plasma Thruster I´m trying to measure the total inductance of a pulsed plasma thruster. According to usual formulas found on books I calculated it should be about 200 nH (very small). The strange thing is that I measured a smaller value than this (about 130...

hey, i was just confused here, which is the right formula for finding the self inductance of a solenoid, given the number of turns, the cross-sectional area, the length, and the current. is it L = Uo x Ur x N^2 x A / L (Uo = mu o, Ur = mu r)?? pls if it is wrong, let me know the right...

Im reading chapter one for physics 2. It says that you can create a charge on a neutral body through inductance. It says that the charged object will make the electrons near it be repeled on the neutral object. So there will be a positive charge near the source object of negative charge. My...

In the figure attached below, the rolling axle, 1.50 m long, is pushed along horizontal rails at a constant speed u = 3.00 m/s. A resistor R= 0.400 Ω is connected to the rails at points a and b, directly opposite each other. (The wheels make good electrical contact with the rails, and so the...

A solenoid has 140 turns uniformly wrapped around a soft iron core, which has a magnetic permeability =750 Uo (mue sub-knot) diameter of 10.0m and a length of 9.00cm. What is the inductance in milli-henry (mH)? Did I set this up right? Using L=(uN^2A)/length, you get...

Hi everyone, I'am trying to find the formulas of the mutual inductance of an one single layer coil (the cross section is rectangular i.e. the wire is rectangular or a round loop with rectangular cross section)on cylindrical winding form. Does anyone know how to calculate this mutual...

I'm having problems trying solve this problem. Consider the two conductor system given below |----------------------------------------------------------------| | <------a-----> | | I2-> ______________...

Hi, All: I am trying to calculate the mutual inductance between the coil (100 turns) and the magnet. Does anybody know any approaches that may lead a satisfactory answer. So far, I have been using Neumann's formula which is the formula for mutual inductance, M, between two loops. I...

I'm stumped by the following problem. To determine the inductance of a coil used in a research project, a student first connects the coil to a 12.0V battery and measures a current of 0.630 A. The student the connects the coil to a 24.0-V(rms), 60.0-Hz generator and measures an rms current of...
