SUMMARY

The discussion centers on the confusion surrounding the identification of positive polarity in a given image, which features a compass and a potential battery or magnet. Participants clarify that a compass cannot determine the polarity of a battery; instead, a voltmeter is required for accurate measurement. The conversation highlights the misconception that a compass points to magnetic north due to its magnetic properties, when in fact it aligns with the Earth's magnetic south pole. The original query remains ambiguous, leading to further speculation about the objects depicted in the image.

PREREQUISITES
  • Understanding of magnetic polarity and its principles
  • Familiarity with the function of a compass in magnetic fields
  • Knowledge of using a voltmeter for electrical measurements
  • Basic concepts of magnetism and its applications
NEXT STEPS
  • Research the principles of magnetic polarity and how it relates to compasses
  • Learn how to use a voltmeter to measure battery polarity
  • Explore the differences between magnetic fields and electric fields
  • Investigate common misconceptions about compass functionality
USEFUL FOR

Students, educators, and hobbyists interested in physics, particularly those studying magnetism and electrical measurements, will benefit from this discussion.

Referring to following image,

Does anyone have any suggestions on which side is positive polarity?

Thanks in advance for any suggestions :>

Science news on Phys.org
could you explain what the picture consists of?
 
The bottom of the magnet, the side the compass is pointing to, is actually a south pole. A compass points towards the North pole of the Earth not because it is magnetically north, but because it is magnetically a south pole and is in the North direction.
 
Polarity is the most confusing concept in my understanding.

Thanks you very much for suggestions :>

Is that a battery in the upper part of the image? is that a magnetic compass in the lower part? If the answers are both "yes", then you cannot determine polarity of the battery using a compass.

A compass moves its needle into alignment with a magnetic field (the earth's, usually).

The polarity of a battery cannot measured using a magnetic compass. You could find the polarity of the battery using a voltmeter, for one example.
 
I think that is a magnet, not a battery.

I think you are right

tho when you look closely at the top thing, I'm wondering if its a flip down lid that covers/protects the compass face ? see the little lugs at 180 Deg spacing

but the original question is so screwball, its really difficult to figure out what the Op really wants to know
