In summary, the conversation is about building a vibrating sample magnetometer (VSM) and the components needed, specifically the detector induction coils and sample holder. The desired specifications for the coils and holder are mentioned, and suggestions for where to find them are given, such as electronic stores or surplus places. Additional suggestions for making the coils and holder using materials like phosphorus bronze wire and G10 tubing are also mentioned. The person asking for advice is also looking for more information on inductance and operating frequency.

Hi,

I am building a vibrating sample magnetometer (VSM) and I have all the components except for the detector induction coils and sample holder. Any ideas where I could get the coils (for cheap)and what to make the sample holder out of?

The induction coils have to have an axial length and outer radius of 1-2cm.

The sample holder has to be rigid 1 1/2ft long with perhaps with a radius of about 0.5cm-1cm. Non magnetic

If any of you have ever built one any advice is appreciated.

thanks

Give us some more hints!

How much inductance, operating frequency of the coils, etc..

Electronic stores and surplus places might have what you want. Even some old piece of equipment.

Polystyrene has excellent electical properties, so a piece of poly tubing might make a good holder.

You could wind your own coils for cheap. with phosphorus bronze wire and GE varnish. And G10 tubing would be good for the sample holder and the coils.

1. What is a Sample Holder and coils for VSM?

A Sample Holder and coils for VSM (Vibrating Sample Magnetometer) is a device used in magnetic property measurements of materials. It consists of a sample holder, typically made of non-magnetic material, and a set of coils that generate a magnetic field to measure the magnetic properties of the sample.

2. How does a Sample Holder and coils for VSM work?

The sample holder is placed inside the VSM, which is a highly sensitive instrument that measures the magnetic response of the sample to an applied magnetic field. The coils surrounding the sample holder generate a magnetic field, and the VSM measures the changes in the magnetic properties of the sample as the field is varied.

3. What are the different types of coil configurations used in a Sample Holder for VSM?

The most common coil configurations used in a Sample Holder for VSM are Helmholtz, Maxwell, and Solenoid coils. Helmholtz coils provide a uniform magnetic field in a specific area, Maxwell coils generate a non-uniform field, and Solenoid coils produce a highly uniform field along the axis of the coil.

4. What are the important factors to consider when choosing a Sample Holder and coils for VSM?

Some important factors to consider when choosing a Sample Holder and coils for VSM include the type and size of the sample, the desired magnetic field strength, the sensitivity of the VSM, and the type of magnetic property being measured (e.g., magnetic moment, coercivity, etc.). It is also essential to ensure that the sample holder and coils are compatible with the VSM being used.

5. Can the Sample Holder and coils for VSM be customized for specific experiments?

Yes, the Sample Holder and coils for VSM can be customized to meet the specific needs of a particular experiment. This can include the design and size of the sample holder, as well as the configuration and strength of the coils used. Customized sample holders and coils can help improve the accuracy and precision of magnetic property measurements for unique samples or experimental conditions.
