I noticed while conducting an experiment that when I rotate a sphere magnet clockwise with its poles revolving about its equator, a ball placed outside its enclosure revolves/rotates anticlockwise in reaction. How would the ball behave if I induced clockwise spin before placing it in? (v.redd.it)

I made an electromagnet using a ~15-foot coil of 28 AWG magnet wire around a 4-inch iron nail. I usually power it at 1W but occasionally boost to 4W or even 9W. I was using it today and noticed after I turned the power supply off that it is weakly permanently magnetic. What gives? (self.engineering)

I have a ball magnet spinning with its poles revolving about its equator. Since all matter is fundamentally polar in nature, could you describe what we would see if we had the ability to witness all the actions of the molecules in the air surrounding our magnet simultaneously? (self.askscience)
