Measurement of magnetic susceptibility by Gouy’s method
Procedure:
- Set up the Gouy balance with the electromagnet and analytical balance.
- Ensure that the balance is zeroed and calibrated properly.
- Measure the mass of the sample tube without the paramagnetic sample and record it.
- Fill the sample tube with the paramagnetic sample and place it in the magnetic field.
- Record the new mass reading.
- Calculate the change in mass (Δm) as the difference between the two readings.
- Note the field strength (H) provided by the electromagnet's specifications or measure it using a Gaussmeter.
- Use the formula provided to calculate the magnetic susceptibility, χm.
Calculations:
Substitute the values of Δm, g, μ₀, H, and l into the formula: χm = (2 × Δm × g) / (μ₀ × H² × l) to calculate the magnetic susceptibility.
Results:
The magnetic susceptibility (χm) of the given paramagnetic sample is found to be … (in appropriate units).
