An Active User Program

The DC Field Facility attracts hundreds of users a year. Here Yuanda Gao and Cory Dean conduct a transport experiment on graphene with a 35 tesla magnet.

Scientists using 35 tesla magnet

Located at MagLab headquarters near Florida State University in Tallahassee, the facility offers users the strongest, quietest, steady and slowly varying magnetic fields in the world, coupled with state-of-the-art instrumentation and experimental expertise.

The facility contains 14 resistive magnet cells connected to a 56 megawatt DC power supply and 15,000 square feet of cooling equipment to remove the heat generated by the magnets. The facility also includes several superconducting magnets operating at millikelvin temperatures. Among these instruments are several record holders, including the 45-tesla hybrid magnet, which offers scientists the strongest continuous magnetic field in the world. The research is supported by magnet plant and cryogenic system operators. Technicians design, build and repair instruments for user research. Scholar-scientists — world-class researchers with their own vibrant research interests — work directly with users to get the best measurements and data.


Our magnets are open to all scientists — for free — via a competitive process and we accept proposals throughout the year.

    Inducing Magnetic Ring Currents in Non-Magnetic Aromatic Molecules

    Magnetic induction is used in technology to convert an applied magnetic field into an electric current and vice versa. Nature also makes extensive use of this principle at the atomic and molecular level giving scientists a window to observe material properties. Using the 25 T Split-Helix magnet, researchers observed changes in the optical properties of organic materials due to currents induced by applied magnetic fields flowing in molecular rings, evidence that could increase the list of materials that could be used in future magnetic technologies.
