Homework Help Overview

The discussion revolves around identifying which of two metals is magnetic, exploring the properties of magnets and magnetic materials.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants consider the effects of different orientations and positions of the metals when brought together. There is discussion about the nature of attraction between a magnet and a magnetic metal, and whether this attraction is consistent regardless of their arrangement.

Discussion Status

Participants are actively engaging with the problem, questioning assumptions about the behavior of magnets and magnetic metals. Some guidance has been offered regarding the orientation of magnets when interacting with metal objects, leading to further exploration of the topic.

Contextual Notes

There is an indication of uncertainty regarding the identification of permanent versus temporary magnets, and how this relates to the original question about the two metals.

Homework Statement
I have 2 pieces of metal in front of me. One is a magnetic metal and the other one is a magnet. I need to know which of the two pieces is the metal and which is the magnet. They look identical and I can't use anything else apart from the 2 metals.
Relevant Equations
none
No idea where to start

Consider different orientations and relative positions in which you might bring them together. What would you expect to observe?

They would attract each other. I'm thinking of balancing them both and make some sort of a makeshift compass but think that's a sketchy solution.

In the same way, regardless of their relative positions and orientations?

Yes I believe a magnet and a magnetic metal will always attract each other. Am I missing something here?

I think you are.
Suppose you wanted to pick up a metal object using a magnet. How would you orient the magnet towards the object?

I've thought of rubbing them together to create a temporary magnet but I don't see how that would tell me which one's the permanent.

If it was for example a bar magnet I'd orient 1 end to the metal object I was trying to pick up.

And I just got it, thank you!

Quite a nice example of knowing the answer intuitively, but not realising you do.
