Is it true that every material can be attracted by a magnetic field provided that the magnetic field is STRONG enough?
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.
Ferromagnetism is a physical phenomenon in which certain materials exhibit a strong attraction towards magnetic fields. This attraction is due to the alignment of the material's atomic dipoles in the same direction.
Common examples of materials with ferromagnetic properties include iron, nickel, cobalt, and their alloys. Other materials such as gadolinium and dysprosium also exhibit ferromagnetism at certain temperatures.
Ferromagnetism is a result of the alignment of atomic dipoles within a material. This alignment can be induced by exposing the material to a strong external magnetic field or by heating the material above its Curie temperature.
Ferromagnetic materials have a wide range of practical applications, including in the production of magnets, electric motors, and transformers. They are also used in data storage devices, such as hard drives and credit cards with magnetic strips.
No, only certain materials with a specific atomic structure and arrangement of electrons can exhibit ferromagnetism. Other types of magnetism, such as paramagnetism and diamagnetism, can be observed in different materials.
