0.5 Tesla (5,000 Gauss) Bench Top Electromagnet (Model EM-50)
The EM-50 electromagnet is our small footprint magnet system. This compact, air or water-cooled (water cooling is required for extended operation), bipolar bench-top system provides a reversible field of 5,000 Gauss with a 20 mm face diameter pole pair and a 20 mm gap between poles. The size of the gap can be adjusted if necessary to accommodate other cryostats or devices. The EM-50 electromagnet is coupled with the MPS-50 bipolar power supply, allowing automatic field reversal Hall measurements. It is continuously controllable over both the current and voltage range windows when coupled to the Hall effect and van der Pauw controller and monitored by the HMS Software.
1.0 Tesla (10,000 Gauss) Bench Top Electromagnet (Model EM-100)
The EM-100 electromagnet is our small footprint, high magnetic field system. This compact, water-cooled, bipolar bench-top system achieves a reversible field of 10,000 Gauss with a 20 mm face diameter pole pair and a 20 mm gap between poles. The gap size can be adjusted if necessary to accommodate other cryostats or devices. The EM-100 electromagnet is paired with the MPS-100 bipolar power supply, enabling automatic field reversal Hall measurements. It remains continuously controllable across both the current and voltage range windows when connected to the Hall effect and van der Pauw controller, and it is monitored by the HMS Software.
1.4 Tesla (14,000 Gauss) Electromagnet (Model EM-150)
The EM-150 electromagnet is our standard high magnetic field system. This water-cooled system achieves a reversible field of 14,000 Gauss with a 38 mm face diameter pole pair and a 20 mm gap between poles. The gap size can be adjusted if necessary to accommodate other cryostats or devices. The EM-150 electromagnet is paired with the MPS-150 bipolar power supply, enabling automatic field reversal Hall measurements. It remains continuously controllable across both the current and voltage range windows when connected to the Hall effect and van der Pauw controller, and it is monitored by the HMS Software.
This electromagnet is strongly recommended for Hall effect experiments where samples with low Hall mobility or high carrier density are expected. Due to the small Hall voltages measured, higher magnetic fields are desired to obtain reliable experimental results. This magnet is excellent for magnetoresistance studies at variable temperatures.
1.4 Tesla (14,000 Gauss) Electromagnet with Extended Gap (Model EM-150EG)
The EM-150EG extended gap electromagnet is a custom high magnetic field system. The extended gap between magnet coils allows for a special arrangement where magnetic field rotational (angle-dependent) experiments are required. This water-cooled system achieves a reversible field of 14,000 Gauss with a 38 mm face diameter pole pair and a 20 mm gap between poles. The spacing between poles can be adjusted if necessary to accommodate other cryostats or devices. The EM-150EG electromagnet is paired with the MPS-150 bipolar power supply, enabling automatic field reversal Hall measurements. It remains continuously controllable across both the current and voltage range windows when connected to the Hall effect and van der Pauw controller, and it is monitored by the HMS Software.

0.5 Tesla (5,000 Gauss) and 0.7 Tesla (7,000 Gaus) Permanent Magnets (Models PM-50 & PM-70)
The PM-50 and PM-70 dipole permanent magnets are low-cost magnet systems. These compact benchtop magnets provide magnetic fields of 5,000 Gauss and 7,000 Gauss, respectively, between flat 50 x 50 mm square pole pieces with a 20 mm gap. The Hall vacuum cryostat slides into the pole gap of the magnet, and measurements can be taken in one field direction. The HMS software prompts the user to remove the Hall cryostat, rotate the magnet, and insert the cryostat back for measurements in the reverse magnetic field direction.
Hall systems with these types of permanent magnets require manual magnet operation.
