I'm reviewing a letter regarding the sheilding of an object using a superconducting magnet as is commonly found in MRI machines. The claim is that the magnetic field created by superconducting windings (wire which is carrying a current and thus creating a magnetic field) and wrapped around an object will prevent radiation heat transfer to the object. It actually says the magnetic field will shield the object from electromagnetic energy including thermal energy and infrared radiation. This winding is thus supposed to shield the object from thermal radiation heat transfer from the environment.
What do you think? Is there any reason to believe a strong magnetic field created by superconducting windings should block radiation heat transfer?
