so basically if there's a bicycle dynamo, the work or energy you the cyclist gave is just the same as the energy that lit up the light? so the energy won't be an issue? please tell me if I am correct
really confused about how energy can be created if a magnet in a coil attracts instead of repel? please go easy on me. how can you produce energy when your magnet attracts the induced magnetic field so it increases the velocity of the magnet so how could that produce an energy out of nothing?
in my study i want to have a new breakthrough about electromagnetic induction. a new idea or new methods that is not known or not famously known. I am in fact cramming about this my due date is tomorrow to pass a topic, been doing so many stuff that i only had this day to study the whole...
okay now i see. if lenz law is not obeyed, then the induced voltage, thus also induced magnetic field would not oppose the original magnetic field, it would instead increase the magnet's velocity and supply more induced voltage and create more kinetic energy on magnet? (im imagining a magnet...
suggestions about what would people would want to know more about electromagnetic induction or waves or like an application say a rail gun but that's impossible for me. I am still reviewing about electromagnetic induction almost done but still can think of what applications could i possibly...
so basically the lenz law says in order not to have change the system, it has to generate or induce a voltage, then creates a current and that current generates magnetic field to cancel out the magnetic field of the original. i got that but..
so this means that if LENZ LAW IS NOT obeyed, there...
Hi i need some striking suggestions about electromagnetic induction or electromagnetic waves. so i first thought about rail guns but i can't actually make a prototype and what do i want to know about that anyway? I really need some ideas? Thanks alot.

I first thought that electromagnetic induction disobeyed the law of conservation of energy since there is another current created by another current by changing it (AC). but then there is Lenz law that says when you have yourself an current and also a changing magnetic flux, there will be an...
Hi! Need ideas for case study about electromagnetic waves
I've been having trouble of finding a case study for electromagnetic waves. Can you please give me neat ideas?
I'm having interest on lasers now so I would want to focus on monochromatic lights but can't think of a new problem to be...
I need some modern physics experiment to be presented on science fair. I have no idea like I am thinking of particle physics like atom smashers but it's impossible to create one for just a month. The cornstarch in a stereo has been gotten by others so I am thinking of photoelectric i don't know...
