Is it true that every material can be attracted by a magnetic field provided that the magnetic field is STRONG enough?
The discussion centers around the magnetic properties of various materials, specifically whether all materials can be attracted by a magnetic field if the field is strong enough. Participants explore concepts such as magnetic susceptibility, types of magnetism, and the behavior of specific materials like copper in strong magnetic fields.
Participants do not reach a consensus on whether all materials can be attracted by a magnetic field, and there are competing views regarding the behavior of specific materials like copper in strong magnetic fields.
The discussion highlights limitations in understanding the conditions under which materials interact with magnetic fields, including the need for specific parameters such as field strength and material dimensions.
nasu said:Try magnetic susceptibility. This is the quantity that may be what you need, for materials with weak magnetism:
- paramagnetic - weakly attracted by a strong magnet
- diamagnetic - weakly repelled
For ferromagnetic materials the susceptibility or permeability may give some information.
So no, not any material is attracted. It may be repelled.
And when is weakly attracted does not mean it is ferromagnetic.
