Magnetization measurements using the field gradient of a high-field solenoid.
By using a high-field solenoid, the force on a magnetic sample resulting from a field gradient becomes large and measurements using the Faraday (or Curie) method are greatly simplified. By using an electronic analog dividing circuit, curves of magnetic moment or susceptibility versus field or temperature can be quickly and easily recorded. Various examples are given.
