Physics - Electromagnetic Induction

Do we have to learn all the experiments on demonstrating electromagnetic induction or just one of them?

There's more than one? I only know the Lenz's Law experiment. I don't recall others..

Leaving Cert Student

There aren't any mandatory ones are there? There is one for each law alright but not on section A as far as I know. I put my section A notes up online they might help you out

If you look at the questions that gave come up on section B, you need to know one of them and to be able to explain the theory of it to a problem eg magnet swinging on string, why does it slow considerably when copper is placed below it?

Yeah you need to know the idea behind it alright but not in the detail you'd need to know the section A ones.

Well there is no mandatory experiment on it so no.

Sure there is, there are a set list of ones that can come up for section A, the method they ask for each may vary, however.

Section B, can contain non-mandatory experiments and ones that you have not necessarily done before but which you should be able to deduce based on certain principles/laws you have learned throughout the leaving cert course.

Alright, thanks. It's just that on the Real Physics book it says Experiments To Demonstrate Electromagnetic Induction and there is a number of different diagrams explaining it (Pg. 310). I ended up just learning the first part of the experiments since it came up in 2004 Q12 (c) and you got full marks if you just explained the first part.
