How Do Non-Magnetic Metals React to Magnetic Fields?

AI Thread Summary
Non-magnetic metals do not react to static magnetic fields, which is why certain options in the discussion are incorrect. However, when there is relative motion between a magnet and a non-magnetic metal sheet, electromagnetic induction can occur, leading to the generation of eddy currents. This phenomenon explains the interaction despite the metal being non-magnetic. The confusion arises from the relationship between ferromagnetism and electromagnetic induction, as the latter can still affect non-magnetic materials under specific conditions. Understanding eddy currents is key to grasping how non-magnetic metals can exhibit responses in dynamic magnetic fields.

More than one options may be correct .

Homework Equations

The Attempt at a Solution


[/B]
Options a) and c) are correct . But I don't understand how non magnetic metal reacts to the magnetic field .

Is it in some way related to ferromagnetism ? But then either both b) and d) should be correct or both incorrect ?

If it is about ferromagnetism then relative motion between the magnet and sheet should not play any role .

Option d) is about relative motion between magnet and the sheet . I doubt whether it is in some way related to change of flux .

They don't, which is why the other answers are not correct.

It is correct and as you said, it is due to electromagnetic induction.

How ? It is a sheet not a loop .

Look up 'eddy currents'.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
