Electromagnets and accessories

• Indexed pole gap settings (ExactGAP™) allow repeatable air gap changes without having to re-calibrate between changes
• Exceptional field intensities achieved with cylindrical or tapered pole caps
• Water-cooled coils provide excellent field stability and uniformity
• Removable pole caps facilitate variable pole face configurations and easy pole cap exchange
• Accurate pole alignment by precise construction of the air gap adjustment mechanism
• The EM-4V/EM-7V yoke designed for optimum air gap accessibility for both top and bottom of the magnet
• Compact size of the EM-4V permits convenient bench-top mounting
• Optional optical access pole caps available
