What it is
Instrument for measuring the magnetic susceptibility of a sample from the rotation a magnetic field produces on a fiber-suspended arm, with the sample at one end and a magnet at the other.
What it led to
- systematic measurement of materials' magnetic properties
- studies of paramagnetism and diamagnetism
- materials-physics laboratory instrumentation
- precedent for modern magnetic balances
