Electromagnets
EM7000S is a HOLMARC New Magnet LAB range high magnetic field PC controlled Dipole Electromagnet that can provide fields above 3.3 Tesla @ 5 mm field gap. Designed to meet industrial, educational, and research needs of very high, uniform field strengths in a wide range of air gaps. The HOLMARC Magnet LAB range dipole electromagnet systems are intended to work based on automated PC controlled operations.
The EM7000S comes with a standard set of 125mm diameter poles which are tapered into 20mm at face. To optimize the magnetic field, several custom pole options are available. Poles are interchangeable and are also available with an axial access bore, as a custom option.
