Quench This is loss of superconductivity of the magnet. It becomes resistant due to high temperatures. Cryogens boil and pass thro quench lines. If switched off, will be rumped (heat high) and quenched to restore the magnetism. Advantages of superconducting magnets High magnetic field 0.5 to 3 tesla No environmental interference Homogeneous magnetic field Good images and high resolution. MRI machine installed away from magnetic objects like computers, met- als, cars and Farady cage used for shielding the machine from other mag- netic fields.
