The electromagnet lesson has spark my curiosity as to whether there are any good labs out there showing the repulsive forces (including strength & practical uses) that can be produce by electromagnets; such as by bullet trains (e.g. Maglev train in China). For repulsive electromagnetic forces: Please share any ideas, labs, practical uses...etc.
Thanks & regards,
