Electromagnets

The Lake Shore EM4 and EM7 series electromagnets (EM) produce variable magnetic fields with a variety of air gap and pole cap configurations. The EM series is ideally suited for integration into customer-designed magnetic test platforms for applications including magneto-optical studies, magnetic hysteresis studies, in-line annealing, Hall effect studies, susceptibility measurements, spin magnetic resonance demonstrations, and biological studies.

The HV series feature continuously adjustable poles, allowing rapid air gap changes to suit individual experiments, and threaded or bolt-on mounting that provides easy pole cap exchange. The EM series incorporate water-cooled coils and precision yokes made of magnetically soft, ultra-pure steel, assuring precise pole cap alignment as well as excellent field homogeneity and stability. The EM7 yoke is oriented at a 45° angle and the EM4 yoke at a 40° angle for optimum air gap accessibility. The EM4 is also compact in size and has steel eyebolts, permitting convenient bench-top mounting to optical tables. Electromagnet product overview...
