Methods, systems, and apparatuses for retaining magnetic properties of magnetic elements while undergoing manufacturing processes are presented. In one embodiment, a manufacturing fixture includes a temperature controlled region suitable for retaining a magnetic element. The manufacturing fixture also includes a cooling mechanism configured to maintain the magnetic element at an acceptable temperature range during a thermally active manufacturing process. The temperature controlled or stabilized region can include a structure configured to receive the magnetic element and a sensor, or sensors. In one embodiment, the sensor can be configured to measure an ambient temperature of the temperature stabilized region. In another embodiment, the sensor can be a magnetic sensor configured to determine a magnetic property of the magnetic element.
