If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Video Description

Even in 2014, the question remains, @!$#& Magnets, how do they work? This video aims to answer that question using no math and only textbook physics and maybe a cute kitten. You will find the answer to what is going on magnets that make them want to fly towards each other based on things which are easily observed and understood. If you want to know more details on what makes the magnetic force work, check out the links at the end of the video - after all how much can I explain in only 5 minutes?

Dear Mr. Hu,

Only one end of a magnet is attractive. The other end is repellent. How much of a bar magnet is neutral? If “electrons” only attract, what causes the other end of the magnet to repel. Could it be “anti-electrons”?

Respectfully,

Joe Fisher
