What is the correct use of mainEntityOfPage schema

I am writing structured data for a magazine. I got this under the Article type:

"mainEntityOfPage": {
    "@type": "WebPage",
    "@id": " https://www.example.com/category" //category of the article
  },

I thought I would mark the category of the article using this. Is this the correct way of using mainEntityOfPage?

No, the value should be the WebPage dedicated to the Article. Both items would typically have the same url, but possibly different @id values (see URL of page vs. post).

{
  "@context": "http://schema.org",
  "@type": "Article",
  "@id": "/articles/42#this",
  "url": "/articles/42",

  "mainEntityOfPage": {
    "@type": "ItemPage",
    "@id": "/articles/42",
    "url": "/articles/42"
  }

}

It might become clearer when looking at the inverse property mainEntity. You would have a WebPage for the current page and provide the mainEntity property to convey what the primary entity on this page is:

{
    "@context": "http://schema.org",
    "@type": "ItemPage",

    "mainEntity": {
      "@type": "Article"
    }

}

When using mainEntityOfPage instead of mainEntity, you simply switch subject and object.
