An electavizer or magmanizer are not standard terms widely recognized in scientific or consumer contexts, so it’s unclear what specific devices you are referring to. If you meant devices related to electronic or magnetic applications, you might find similar products at electronics retailers, online marketplaces like Amazon, or specialized suppliers in industrial equipment. For specific models, checking with manufacturers or industry-specific distributors would be beneficial. If you have more context or details, that could help refine the search.
