Creating a Magnetic Snow Globe: Lightweight Options

Click For Summary

Discussion Overview

The discussion revolves around the creation of a magnetic globe, conceptualized similarly to a snow globe, with a diameter of approximately 30 cm. Participants explore various lightweight options for constructing this globe, considering the magnetic properties and potential applications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests using an electromagnet to achieve the desired magnetic properties, noting that the current will depend on the strength and direction of the magnetic field.
  • Another participant inquires about the intended use of the globe and whether the mechanism for creating the magnetic field should be visible or hidden, indicating a consideration of design choices.
  • A suggestion is made to use disk magnets glued to the surface of a balloon as a lightweight option for the globe's construction.
  • There is a question about whether the globe is intended for educational purposes, such as demonstrating Earth's magnetic field.
  • One participant emphasizes the need for clearer explanations of the project's goals to receive more targeted advice.

Areas of Agreement / Disagreement

Participants express varying ideas about the construction methods and intended applications of the magnetic globe, indicating that multiple competing views remain without a consensus on the best approach.

Contextual Notes

Participants have not fully defined the parameters of the magnetic field, such as its direction and strength, nor have they resolved the implications of using different construction materials or methods.

I'm trying to make a magnetic globe (magnetic from outside) with diameter of about 30 cm. Please imagine it as a snow globe, while it is magnetic as well :). I'm wondering about the options to make it, as light as possible.
Please feel free to suggest tags here, if I'm missing anything or I have put the message in the wrong thread :)
Thanks.

Do you have any preferences for the direction and strength of magnetic field?

A good way to make such a globe is to have an electromagnet. The current will depend on the strength and direction of the magnetic field.

How do you plan to utilise the globe? Can it have wires wound around it on the outside? Or should the mechanism of creating the B-field be hidden inside the globe?

If you want to make it light then you should be thinking in terms of electromagnets.

You could glue disk magnets to the surface of a balloon.

If you want better quality answers, you'll have to explain better what you are trying to accomplish.
