There are different classes of magnetic matterials. Invest a little bit of time to understand dia, para, ferro, anti ferro, and ferri magnetism. I will publish a supporting APP with this: WebAppForThisPodcast seen below This is a cutting from the APP, it uses new maths , you can expand any question for details. magnetic matterials1st Question "What are the elements of a complete knowledge base for magnets and magnetism"1st Response "You can find out about the history"1st Question "What are the key Eras of development?"4th Response "The quantum Era"--------- I will do a podcast soon explaining the new maths behind the generation of these APPs.  Any questions post a comment. http://lessonpeer.com/drhillteach/Magnetic%20Matterials.mp3

Robert Brown discovered the nucleus of cells, and observed small particles being jostled by atoms. He is the most important Botanist of Australia, that no one remembers.... http://lessonpeer.com/drhillteach/The%20guy%20behind%20Brownian%20Motion.mp3

Newton didn't have the mathematical tools of equations, so his descriptive approach is ideal for a non mathematical introduction. This podcast lays out the necessary foundation work to move forward. http://lessonpeer.com/drhillteach/Newton's%20First%20Law%20(of%20Inertia).mp3

This is really important as it really gets to the birth of the concepts of Force and Mass looking forward from Newton. http://lessonpeer.com/drhillteach/Newton's%20Second%20Law%20(of%20Force%20and%20Mass).mp3

Newtons' first law leads to inertial frames. Actually listening to student's questions, requires honest answers here. I put forward limited and pseudo inertia frame. The Newton two is given a "d and t" and we declare work, kinetic energy, impulse and momentum http://lessonpeer.com/drhillteach/What%20can%20I%20do%20with%20Newton%20One%20and%20Two.mp3

Well this applies to a system of bodies, so the earlier work of talking about what a body is and impulse leads to this momentum law. I have real problems with just getting students to rote learn this. http://lessonpeer.com/drhillteach/Newton's%20Third%20law%20(conservation%20of%20momentum).mp3

#CosmosMagasine Looks at a guy who is really pushing green energy in Australia. You can hear the rain in the back ground. http://lessonpeer.com/drhillteach/Career%20of%20a%20key%20Energy%20Visionary.mp3

Priestly discovered oxygen by keeping a mouse alive by heating mercury oxide with a magnifine glass. Nowadays we keep you alive at home with the wonder material of zeolite. http://lessonpeer.com/drhillteach/Oxygen%20life%20support.mp3
