there is no widely recognized household appliance called a "magnetic washer." It is possible that new technologies or inventions have emerged since then, but as of that time, no mainstream washing machine used magnetism as the primary mechanism for washing clothes.
In traditional washing machines, the washing process involves a combination of water, detergent, and mechanical action (agitation and spinning) to clean the clothes. There are also modern washing machines that use advanced technologies like ultrasonic cleaning, but magnetism is not a common method for washing clothes.
If the term "magnetic washer" has gained popularity or changed in meaning , I recommend looking for the latest information from reliable sources or conducting a specific search for any recent developments related to this term.
