Lake Shore Coils

Lake Shore's line of standard and custom fluxmeter sensing coils includes 64 mm, 152 mm and 300 mm in Helmholtz coils and 30 cm² and 100 cm² search coils.

Helmholtz Coils (Field Standards)
Lake Shore offers four Helmholtz coils for field standards: 64 mm, 152 mm and 300 mm in diameter single axis, and the MX-2X-10 double axis coils.

Features:

• Standard field coil (field generation)
• Field strengths from ~12 G to ~ 30 G
• Field accuracy of 0.75%
• Field uniformity of 0.5%
• Single axis configuration with 64 mm (2.5"), 152 mm (6") and 300 mm (12") diameter coils

Helmholtz Coils (Magnet Moment Measurement)
Lake Shore offers three Helmholtz coils for fluxmeter moment measurements, 6 4mm, 152 mm and 300 mm.

Features:

• Inspection and research of magnets (measure moment)
• Calibration accuracy of 0.75%
• Single and 2-axis configurations with 64 mm (2.5"), 152 mm (6") and 300 mm (12") diameter coils
• Use with Model 480 Fluxmeter only

Search Coils
The 100 cm² field probe is the most common, while the 30 cm² field probe is useful for measurements in narrow gaps or where field gradients dictate the use of a smaller coil diameter.

Features:

• Inspection and research of magnets (narrow gaps or field gradients)
• Calibration accuracy of 0.25% or 0.35% (model dependent)
• Offered in 100 cm² and a 30 cm² area-turn configurations
• Use with Model 480 fluxmeter only
