Magnetic Susceptibility Lookup
Determine the dimensionless volume magnetic susceptibility chi = M / H (SI) from an induced magnetization in amperes per meter and a magnetizing field strength in amperes per meter, and convert it to CGS electromagnetic units (chi_cgs = chi_SI / 4 pi). A negative value indicates diamagnetic behavior.

A negative value indicates diamagnetic behavior.

When to use Magnetic Susceptibility Lookup
Use this geological calculation for a transparent first-pass interpretation of measured rock, soil, fluid, well, stratigraphic, isotopic, geophysical, or seismic data under an explicitly selected model.
- M
- Induced magnetization magnitude in amperes per meter.
- H
- Magnetizing field strength in amperes per meter.
How Magnetic Susceptibility Lookup works
Determine the dimensionless volume magnetic susceptibility chi = M / H (SI) from an induced magnetization in amperes per meter and a magnetizing field strength in amperes per meter, and convert it to CGS electromagnetic units (chi_cgs = chi_SI / 4 pi). A negative value indicates diamagnetic behavior. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- chi SI
- Volume magnetic susceptibility, dimensionless (SI).
- chi CGS
- Volume magnetic susceptibility in CGS electromagnetic units.
Limitations and assumptions
- Hand-specimen properties such as hardness, streak, luster, cleavage, density, and magnetism can overlap among minerals and vary with impurities, weathering, grain size, and measurement. Identification should combine several tests and, when needed, analytical methods.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Compare independent measurements and models, retain units and analytical metadata, propagate uncertainty, and validate interpretations against logs, cores, maps, laboratory data, or field observations.
