      I know that heat can reduce a magnet but to  want to know. Can magnets be welded? If yes or no, explain the science behind it.

      I can’t see welding being great for magnets

      I know you can solder to magnets, you just have to be careful not to get them too hot, I guess welding to them is not going to be a good idea as explained above.

      I’m surprised you can even solder to them. You can make a curie engine with an iron ring a magnet and a candle. The candle is enough to disorganise the domains in the ring so that the attraction of the magnet is biased to one side hence the motor effect.

      I have never heard of a Curie engine. I will have a go at making one. I did add this demo to my magnetic lessons recently. I just realised my straight reference line failed!

        it’son my list of jobs, haven’t got round to it yet. The pendulum type are easier but not as much fun.

         

        I have a nitinol engine  🙂
