An air pressure fixed coil for magnetic resonance imaging has a surface on which an air pressure fixing device is arranged. The air pressure fixing device is in communication with a control switch, that is operable to actuate the air pressure fixing device to generate a negative pressure or to restore a normal air pressure, so that the air pressure fixing device is suctioned and fixed onto an object, or is released from the object.
