- 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
- 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
- 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
- Difference between enthelpy, Helmholtz free energy, Gibbs free energy
I am study chapter 5 of An Introduction to Thermal Physics by Schroeder and I am having trouble understanding his explanation of the differences between enthaply, Helmholtz free energy, and Gibbs free energy Schroeder defines enthalpy of a system as its energy plus the work needed to make
- Helmholtz Resonator: attenuation vs. amplification
Hello guys, I read the other threads about HR, resonances and so on, but I couldn't find a clear explanation of what the practical implications of using a HR are From one side, HR is described as a "reactive element", used in several contexts to attenuate a specific noise by means of
- 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
