Laboratory solenoid DX series

double-coilelectromagneticcompact

A solenoid is a helical coil electromagnet that generates a controlled magnetic field when an electric current passes through it. Dexinmag's solenoids deliver compact, uniform axial magnetic fields and support both AC and DC operation for research and industrial applications.

Features:

• Generates a uniform axial magnetic field over a volume when designed and wound correctly.
• Compact form factor with high achievable field strength; predictable linear relationship between current and magnetic field.
• Capable of producing both AC and DC magnetic fields; low-inductance variants facilitate high-frequency AC or impulse fields.
• Customizable geometries and winding patterns to meet specific uniformity, sample size or integration constraints.

Types / Variants described:

• Highly uniform solenoids: optimized winding combinations to increase uniform field region while reducing overall coil length — suited to long-sample measurements.
• No-magnetic-moment (nested) solenoids: two or more nested coil groups arranged to cancel external magnetic moment, reducing stray fields and minimizing magnetization of nearby components.
• AC / impulse solenoids: compact, low-inductance structures designed for high-frequency AC or impulse magnetic-field generation.

Main applications:

• Generation of reference magnetic fields for testing and calibration.
• Evaluation and testing of magnetic shielding effectiveness.
• Electromagnetic interference (EMI) simulation and test experiments.
• Calibration of Hall sensors and various magnetometers.
• Investigation of biomagnetic signals and material magnetic properties.
• Magnetization/demagnetization of magnetic materials; use as electromagnets or inductive components.

Technical specifications:

• Uniform axial magnetic field optimized for relatively narrow, elongated samples.
• Designs available for continuous DC, AC and pulsed/impulse field generation.
• Low-inductance options to enable higher-frequency magnetic-field operation.
• No-external-moment (nested) configurations to minimize stray fields and environmental interference.
• High field density within reduced coil volume compared with conventional winding approaches.
• Custom manufacturing available to meet application-specific uniformity, geometry and integration requirements.
