Hi, I would appreciate some help here as its been some 25 years since leaving school and I am now expected as part of my duties and training for a youth leader in a cub scout pack to provice some activities in relation to Beaver Cubs and activity badges.
Subject... Magnets.
Now I appreciate that this question may have been asked and please don't shoot me down in flames, the old brain cells have had an addling of 20 odd years and the medication I am on doesn't help with memory.
Magentic force / energy, how is the energy derived in a magnet?
I have watched a youtube posting by the "how its made" TV show on how magnets are made, it however does not answer the burning question of where the energy comes from...
Ignoring any input energy from the user, if two opposing fields come together to repel and likewise come together to attract, where does this magnetic force get its energy from or whatever you want to call it to pull each other together or push away.
I have some practical demonstrations to show things like magnetic line of force / energy and made a rudimentary electro magnet and demonstrations of temporary magnets, Lenz's Law with the magnet going down a copper pipe which is pretty cool.
My worry is that one or more of the Beaver cubs will ask me the question of where do magnets get their energy from and my two options are to suggest we research this further or have the actual answer and I prefer the answer route, keep those hungry minds fed and fattened up :)
So your help is appreciated, anything that you can help me with, you don't really want to see me begging on my knees do you?
Please, keep your answers in terms that I can understand, I read one post and my head imploded.
