A changing Magnetic flux induces an Electric field. This can create a current in a wire to power a

This is the idea behind power generators: • Spin a magnet with a mechanical source (e.g. water) • The changing Magnetic field induces an AC current in nearby wires • The current can then be sent to an "outlet" (or applied directly as shown here)pic.twitter.com/u6KuTAouvi
This is precisely how "induction stoves" work • The oscillating magnetic field wirelessly induces a current in the pot • The current flowing through the pot results in resistive heating The coolest thing about induction stoves is that the stovetop itself doesn't get hot!pic.twitter.com/sLC3hDyAun
You have a gift for explaining math and science. Maybe you’re a young Carl Sagan?
hey thanks much!
Nothing Freudian to see here..
Underrated
Electromagnetic induction...
yes, that's the technical term...
I think you should remove “no battery needed”. People might think you can create this effect without energy input or that even worse you can get more out than you can put in.
well there is no battery needed! you need to put in work by accelerating the magnet
