  • Design a Helmholtz Coil: Step-by-Step Guide - Physics Forums
    Dear Sirs, I was asked to design a Helmholtz coil Being an electronic engineer, I can design electronic circuits but I have no idea about designing Helmholtz coils Can you help me by suggesting a paper or article that describes a straightforward, step-by-step method for designing these
  • Calculating B:I for Helmholtz coils - Physics Forums
    Homework Statement I've completed an experiment where the dependence of magnetic field strength ##B## on current ##I## is measured at the midpoint along the axis between two Helmholtz coils (separation distance = coil radius ##r##) I got the expected linear relationship from the data but am
  • Difference between enthelpy, Helmholtz free energy, Gibbs free energy
    The discussion focuses on clarifying the differences between enthalpy, Helmholtz free energy, and Gibbs free energy as defined in Schroeder's "An Introduction to Thermal Physics " Enthalpy is described as the energy required to create a system at constant pressure, while Helmholtz free energy pertains to systems at constant temperature, allowing for heat extraction from the environment without
  • Change in entropy, Gibbs and Helmholtz in an isothermal compression
    Homework Statement Determine the change in the entropy, Helmholtz free energy, and Gibbs free energy, when a mole of ideal gas is compressed from 1atm to
  • Vector field and Helmholtz Theorem • Physics Forums
    Helmholtz theorem states that the same vector field can be written as the gradient of a scalar field + the curl of a vector field which can be obtained through volume integrals involving the fields and
  • Helmholtz pair, magnetic field in 3D - Physics Forums
    The discussion centers on the Helmholtz coil arrangement and its magnetic field characteristics in 3D Participants debate the shape of the magnetic field, with some suggesting it appears cuboidal while others argue it is cylindrical The field is noted to be strongest near the coils and more uniform at the center There is a suggestion to use simulation software like COMSOL to visualize the
  • How to Determine the Magnetic Field of Helmholtz Coils?
    Homework Statement We have 2 circular loops, each of radius R with current I in same direction This is called a Helmholtz coil The loop axes are along the z axis and the centers are at z=+ -s 2 Find the magnetic field along the z axis between the 2 loops Homework Equations
  • How Is the Magnetic Field Calculated at the Midpoint of a Helmholtz . . .
    Homework Statement The picture shows (there's supposed to be a pic) a Helmholtz coil consisting of two circular coaxial coils, each of 200 turns and radius R = 25 0 cm, separated by a distance s = R The two coils carry equal currents i = 12 2 mA in the same direction Find the magnitude
  • What materials are best for building a Helmholtz coil?
    Hello PFs, I need to build some Helmholtz coils, and I was wondering if anybody here had suggestions on what to make the actual rims that hold the wire in a coil are generally made out of? So far its been suggested that I use bicycle rims, but even that creates a question--aluminum or steel
  • Origin of harmonics in Helmholts-type resonators - Physics Forums
    With the Helmholtz resonator, the pressure in the body is uniformly changing up and down, and as it does so, the plug of air in the opening is oscillating up and down There are no nodes, and you do not have a situation where the pressure is rising in one part of the resonator and falling in another (with a node where the pressure is not changing)
