Is there a material that blocks or reflects magnetic fields such as a field from a neodymium magnet?

Do you have a specific problem that you wish to apply this to?Chemics said:Is there a material that blocks or reflects magnetic fields such as a field from a neodymium magnet?
DaleSpam said:In the construction of passively shielded MRI suites we call it a shielding material. On one side of the shielding you may have a field of several tesla and on the other side a field of several nanotesla. So to me it seems fair to call that "blocking" the field.
Obviously reflecting is the wrong word, since that refers to a wave behavior. But to me "blocking" seems close enough to "shielding".
DaleSpam said:You shouldn't need any shielding for something like that. Try http://rsinventionlab.com/archives/126". It may do the job for $15 or so.
A magnetic field is an invisible force that surrounds a magnet or a current-carrying wire. It is responsible for the attraction or repulsion of other magnetic materials.
Magnetic fields are created by moving electric charges. In a neodymium magnet, the atoms are aligned in a specific way to create a strong magnetic field.
The strength of a magnetic field depends on the distance from the magnet, the size and strength of the magnet, and the material it is interacting with. A neodymium magnet has a strong magnetic field due to its composition and size.
The strength of a magnetic field is measured in units of Tesla (T) or Gauss (G). A neodymium magnet can have a field strength of 1.25 Tesla or 12,500 Gauss.
Neodymium magnets have various applications in industries such as electronics, healthcare, transportation, and renewable energy. They are used in speakers, hard drives, MRI machines, electric motors, and wind turbines, to name a few.
