How would life evolve on a planet or other place with a high magnetic field? (It should be a field strong enough to attract tools and weapons and stick them to the ground.) The life forms that would live there (including humans) will have to use cooper tools, so the field must be of 5 Teslas at least).

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

  • $\begingroup$ As asked, this is too broad. Even if you boil it down to just two questions (can life biologically evolve on a planet with a 1 tesla magnetosphere, and can life develop metal tools past the copper age on such a world?), it's still two broad (SE's model is one-specific-question/one-best-answer). As written, this question could reasonably require volumes of books to answer. I'm happy to retract my too-broad vote if you edit your question down to a single, specific question. $\endgroup$ – JBH Dec 29 '18 at 18:39

    $\begingroup$ @EdwardConstantin, yes. Please include all details in the question. Remember, things are attracted to magnetic poles, not the sides of the magnet. Therefore, nothing will ever snap to the ground. But magnetic materials would align themselves along the magnetic field lines. If you threw an iron rod into the air, it would snap to the field alignment - then fall to the ground per the planetary gravity. Compasses would be remarkably accurate. $\endgroup$ – JBH Dec 29 '18 at 21:40

    $\begingroup$ @chaslyfromUK. :-) Now, now, we're only talking about the magnetics. $\endgroup$ – JBH Dec 29 '18 at 21:40

    $\begingroup$ @Edward Constantin Copper tools - in such a strong magnetic field, every time one was moved around, it would move just fine in any direction but it would resist being twisted across the field lines and would generate such high internal eddy currents that it would melt. Hellava weird place to swordfight. $\endgroup$ – Fay Suggers Dec 30 '18 at 5:57
