- Yesterday, I have grouped you according to your gender. And I know you are wondering why... We are going to have a group debate now. Our debate is all about Who has a greater contribution to the development of electromagnetic wave theory: Oersted or Maxwell? Boys group are assigned to defend Oersted while the girls will defend Maxwell. Boys will be the first to defend then the girls. After presentation of arguments, will presume.
- And so are we ma'am.
- The boys are ready ma'am.
- That is why Hans Christian Oersted has a greater contribution. Without him, electromagnetic field would not be discovered and scientist will remain to the thought that electricity and magnetism are unrelated. Without him, Electromagnetic wave theory would not be possible.
- He is Danish physicist and chemist who discovered that the electric current in a wire can deflect a magnetized compass needle, a phenomenon the importance of which was rapidly recognized and which inspired the development of electromagnetic theory.
- When Maxwell used this field theory to assume that light was an electromagnetic wave, and then correctly deduced the finite velocity of light, it was a powerful logical argument for the existence of the electromagnetic force field. That is why he has the greater contribution because without him we would not know that coupled together electric and magnetic fields will form electromagnetic waves.
- He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves. Maxwell discovered that a changing magnetic field will induce a changing electric field and vice versa.
- I am sure that Maxwell is better!
- No, Oersted has greater contributions!
- As you see class, different facts arose and you have defended you sides very well. But class, please bear in mind the two of them are not the only proponents of this theory. This includes Ampere, Hertz and Faraday. Also please do not forget that all of them have great contributions with uniqueness. Not only one of them but all of them. Without them, technology would not be improved as how it is now today. That's it for today class, Goodbye
