Magnetic Field Coil

Product Detail:

DXMC-1MF Helmholtz Coil

Product Introduction:

Typical uniaxial Helmholtz coil is composed two coils with the same number of turns,same  winding method, radius equal to the coil spacing. DXMC- MF series Helmholtz coils usually is used to produce magnetic field whose designated volum is relatively large, uniformity is relatively high, but the value of the magnetic field is weak. Users can use this field to complete all kinds of experiments and the simulation of weak magnetic field. Its main application:to offset the earth magnetic field,to judge magnetic shielding effect, magnetic coefficient of electronic equipments, calibration for fluxgate magneticmeter and navigational equipments, study of biological magnetic field.

Specification for example: DXMC-1MF36 Helmholtz coil,magnetic field 0-18.5Gs.

Routine constants of coil: K=0.2023 (cm), Physical radius of coill R=181mm.
