Magnets -- Experiments with sheets and particles

Click For Summary

Discussion Overview

The discussion revolves around the concept of using magnetic sheets to create educational tools for teaching letters and vowels. Participants explore the feasibility of designing magnetic boards that can attract specific letters based on their magnetic properties, with a focus on the idea of "charging" the boards and letters in a way that allows for selective attachment.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant proposes cutting A4-sized magnetic sheets into circular shapes and questions whether it is possible to create a positively charged and a negatively charged magnetic board.
  • Another participant seeks clarification on the meaning of "positively charged" and "negatively charged" in the context of magnets, suggesting a potential misunderstanding between electrical charge and magnetic poles.
  • A participant explains the educational project, describing the goal of having letters that can only attach to specific boards based on their magnetic properties, likening the concept to the attraction and repulsion of charges.
  • There is a suggestion to avoid using the term "charges" for magnets and instead use "poles," emphasizing the distinction between magnetic dipoles and electrical charges.
  • Participants discuss the need for a sketch to clarify the configuration of the boards and how they would function in the proposed educational setting.

Areas of Agreement / Disagreement

Participants express some confusion regarding terminology and the underlying concepts, but there is no clear consensus on how to implement the proposed idea. The discussion remains unresolved regarding the specifics of creating the magnetic boards and the terminology used.

Contextual Notes

There is ambiguity in the use of terms related to magnetic and electrical properties, which may affect the understanding of the proposed project. The discussion also lacks a detailed description of the physical setup and operational mechanics of the proposed magnetic boards.

Hello

I have magnetic sheets A4 sized that could be bent but not enrolled, having a thin thickness.

I want to cut them in a circular shapes.

The idea, is there any possibility to make one of them (or other material same physics) positively charged and second negatively charged; then have small magnetic particles group of them is positively charged while others are negatively charged such that the + circular paper attracts only - poles and vice-versa?

In other words, can we make dipoles, first considered as N other considered as S from the magnetic papers, while we have small magnets equally composed of same material but different charges?

Thanks in advance

I need to clarify what you mean by "positively charged" and "negatively charged" magnetic plates. Do you mean you are hooking them up like a parallel plate capacitor and applying a voltage difference to them? Or are you using the word "charged" to try to describe the magnetic north and south poles? I'm having trouble parsing and understanding what you are asking about.

Also, could you maybe Upload a sketch of the geometry you are asking about? Thanks.
 
Hello berkeman

I'm sorry for not being clear. I think your second explanation aims at my point: to describe magnet North and South.

It's a school educators project: you should design two differently charged magnetic boards, then attach a small magnet under alphabetical letters.

The teacher for example if wanting to examine kid learning about vowels, he asks him to set letters under different categories of vowels and other types of letters.

Once done, the teacher tells the student if he made any mistakes by showing him that the wrong letters didn't get attached to the board he referred to.

I want to charge the letters to only get attached to magnetic board "1" and other letters to be only able to attach to magnetic board "2" for example.

How is this idea be implemented?

As it is familiar, two identical charges repulses, two different charges attracts. In our case the vowels should have + charge and their corresponding board should be - charged.

Awaiting your comments

It would help if you could sketch the configuration of the two boards, to clarify how they will be set up and work.

And it would be a little better not to use the word "Charges" in the context of magnets. Instead, use the word "Poles" A magnet has a positive pole and a negative pole. That's why we call them a magnetic dipole. :smile:

Do it kind of sounds like you would like to design these boards so that some characters will stick to one board and not the other? Is that the main design goal?
