Impart Magnetizations on Highly Coercive Materials with Precision and Control
Pulse Magnetizer (PM) Features and Functionalities
Exploring the Capabilities of the Pulse Magnetizer for Magnetic Treatment
A Pulse Magnetizer (PM) is a fundamental instrument in any rock and paleomagnetic laboratory. It applies a strong magnetic pulse to rock samples, aligning their magnetic moments in the desired direction. This capability makes it ideal for Isothermal Remanent Magnetization experiments, especially when dealing with highly coercive materials.
The new Pulse Magnetizer from Mag-Instruments is fully digitally controlled and can be operated either through its built-in graphic LCD interface with dedicated knobs and buttons or remotely via a connected PC. Seamless integration with our comprehensive laboratory software suite allows you to control all of your instruments from one unified system—a feature that sets the PM apart from any other solution on the market.
Each system can be delivered with custom-designed coils tailored to various sample sizes, as well as specially made sample holders to ensure comfortable handling of any type of specimen. Additionally, every coil comes equipped with a built-in temperature sensor. Constant temperature monitoring lets us adjust the internal capacitor’s voltage and maintain a stable magnetic pulse, ensuring reliable and consistent experimental results.

Essential Tool
Pulse Magnetizer Application Fields
The Pulse Magnetizer’s versatility and precise field control make it an indispensable instrument across multiple scientific disciplines. By enabling the controlled and repeatable magnetization of a wide range of samples, it supports accurate and insightful research in the following areas:
Paleomagnetism
Use the Pulse Magnetizer to impart a stable remanent magnetization to oriented rock samples or archaeomagnetic materials. This controlled magnetization aids in reconstructing past geomagnetic field variations, deepening our understanding of Earth’s magnetic history.
Rock Magnetism
Apply a well-defined magnetic field to rocks, sediments, and soils to investigate their fundamental magnetic properties. By precisely setting the magnetization, researchers can more effectively study factors such as coercivity and remanence, advancing the field of rock magnetism.
Environmental Sciences
Magnetize soil and sediment samples to examine how environmental changes—such as pollution levels or climate variations—affect their magnetic signatures. This approach supports a clearer understanding of environmental processes and their historical records.
Archaeology
Introduce controlled magnetization to soil and archaeological artifacts to enhance the interpretation of magnetic anomalies detected in archaeological surveys. This process improves the accuracy and resolution of magnetic mappings, aiding in more informed archaeological interpretations.
Material Sciences
Create stable magnetizations in ferromagnetic materials to investigate intrinsic magnetic properties like coercivity, saturation magnetization, and grain interactions. Such precise magnetization control is crucial for developing advanced materials and improving their performance in various applications.
