Homework Statement Find the mutual inductance between an infinitely long wire and a single loop of wire separated by a distance d. (radius = a) Homework Equations The Attempt at a Solution I've adjusted the magnetic flux density to a coordinate system to make everything easier B =\frac{...

Does anyone know how to code the following? I have six inductors in series and would like to couple them to one another. i.e. L1 1 2 1u L2 2 3 1u L3 3 4 1u L4 4 5 1u L5 5 6 1u L6 6 7 1u Ideally I'd like to do: K12 L1 L2 0.3 K23 L2 L3 0.4 K34 L3 L4 0.2 K45 L4 L5 0.5 K56 L5 L6 0.4...

Homework Statement For coupled coils in this arrangement (illustration attached), show L_{eq} = \frac{L_1 L_2 - M^2}{L_1 + L_2 - 2M} Homework Equations KVL (mesh analysis) The Attempt at a Solution As you can see, I get to a final answer - which is not exactly the same...

Homework Statement A square, single-turn wire coil L = 1.13 cm on a side is placed inside a solenoid that has a circular cross section of radius r = 2.77 cm, as shown in the figure below. Basically a big circle with a square in the center. The solenoid is 20.0 cm long...

Homework Statement Find the mutual inductance in air between a long straight filament and a coplanar square loop, 10cm on a side, with its nearest edge parallel to and 10cm from the filament. Homework Equations What equations should be best in solving this problem? The Attempt at a Solution...

I am a student of the electrical engineering in the university of Munich. I tried to solve a homework but I have some difficulties. I have tried to use different methods. unfortunately, unsuccessfully. I will be very glad if you could help me. in fact I wanted to calculate the mutual...

Hello All, I did a simple mutual inductance experiment recently which involving two coils (5 turns each) in series with a high frequency signal (MHz range) running through them. One coil is directly connected to function generator via a co-axial cable, and the other coil is connected to...

In illustrating mutual inductance, there is a primary coil and a secondary coil, which houses an induced current. In applying Lenz’s Law to the direction of the secondary coil’s induced current, the status of the switch must be taken into account. If the switch is closed, does the secondary...

Homework Statement During a 65 ms interval, a change in the current in a primary coil occurs. This change leads to the appearance of a 6.0 mA current in a nearby secondary coil. The secondary coil is part of a circuit in which the resistance is 12 . The mutual inductance between the two coils is...

Hi..I am new here and I am really thankful for any help that I may get :blushing: I am stuck in a problem of mutual inductance. It seems fairly simple, yet I cannot get the correct answer. Two coils are close to each other. The first coil carries a time-varying current given by I(t) =...

It's electromagnetics time again. I'm horribly stuck on a homework problem. It has to do with mutual inductance, and I know how the problem works conceptually, but I'm having a difficult time with the mathematics. The problem:A very long (read: infinite) wire is a distance d from the center of a...

I have 2 inductors in series...iron core...iron yoke...with a capacitor in parallel. For best mutual inductance, does it matter which direction each coil is wrapped...or maybe a better question would be how do you insure that the poles will be opposite every cycle so they are not working...

I'm getting confused over the formal definition of mutual inductance. I've googled and searched a lot of sites, but I still don't understand, so I'm hoping someone here can explain it to me in plain English! In our lecture, this was the formula given for mutual inductance: L_{12} =...

I have my question,solution and the problem I faced in the attachment that followed.Thanks for anybody that spend some time on this question.

Two coils are wrapped around the same cylinder form. When the current in the first coil is decreasing at a rate of -.242A/s, the induced emf in the second coil has a magnitude of .00165 Volts. What is the mutual inductance? What I did: E_2 = -M(\frac{d_i_1}{d_t}) .00165/-.242 = -M...

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...
