Designing High School Lenz's Law Experiment

AI Thread Summary
The discussion focuses on maximizing the educational impact of a Lenz's law experiment in high school physics by using magnets dropped through long copper tubes. The primary aim is to calculate the magnetic force and field strength with minimal additional equipment. Participants suggest leveraging the setup to observe the slowing effect of opposing magnetic fields while measuring distance and time. The goal is to derive calculations related to Fnet and magnetic field strength effectively. Overall, the conversation emphasizes practical experimentation to enhance student understanding of electromagnetic principles.

I teach high school physics and I would like to get maximum mileage out of my Lenz's law experiment/demonstration.

I am going to get the students to drop magnets down a long copper tube to calculate the magnetic force using distance, time etc and making a direct calculation using Fnet=...

What I'd also like to be able to do is use this set-up in some way to calculate the magnetic field strength of the magnets.

Can anyone think of a way to achieve this without the addition of a lot of extra equipment?

Thank you. That is a good demonstration.

I am planning to use long copper tunes to show the slowing effect due to the opposing fields and was wondering if I could incorporate this set-up and get to the strength of the magnets through that.

Thread 'Gauss' law seems to imply instantaneous electric field propagation'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'A scenario of non-uniform circular motion'

(All the needed diagrams are posted below) My friend came up with the following scenario. Imagine a fixed point and a perfectly rigid rod of a certain length extending radially outwards from this fixed point(it is attached to the fixed point). To the free end of the fixed rod, an object is present and it is capable of changing it's speed(by thruster say or any convenient method. And ignore any resistance). It starts with a certain speed but say it's speed continuously increases as it goes...

Thread 'Do electron density waves accompany EM waves in coaxial cables?'

Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
