    Anyone can heelp me out a little

    Urgent help please..

    The Meissner effect is the expulsion of all field lines from within a superconductor. In my scenario im placing the magnet onto an already cooling material, this surely cant be the meissner effect

    Urgent help please..

    Yea, sorry my bad, I mean, why does the magnet remain in its position? Its surely not the meissner effect taking place here

    Urgent help please..

    Anyone experienced with the experiments done with cooled supeconductors, can you explain the experiment with a little detail where they place a magnet over an already cooled superconductor? I have an explanation myself but theres alot of confliction between a couple people i know.

    Are type 1 and type 2 superconductors ...

    Are type 1 and type 2 superconductors specifically in our syllabus?

    Someone help with this Q!

    If i place a magnet over an already cooling superconductor. The magnet repels by the production of eddy currents, but what keeps it in the position?

    Help with this Q!

    Why is it not a positive sin non phase shift?, given that faradays law is (- n (change in flux) )

    Help with this Q!

    If i gave you a magnetic flux vs time graph as a positive cosine non phase shifted function, that is its initially at a maximum. What is the induced emf graph?

    Should I do 4U maths?

    Relax, its not that hard. Definitely go for it.

    Chances of Plank Einstein Debate?

    Hello! Could anyone give their thoughts on the possibility of the Plank Einstein debate on science's involvement in political affairs question coming up? Its such a burden to remember, even if its just key points.. In my opinion it has no physics involvement at all

    2017 HSC Mathematics Paper thoughts

    This is true, we never go over the case of R=0, but then the man spits a good point, 3 marks for that 0 < a < 4 seems a little dodgy.

    Combinatorics "Piles"

    The reason you ever divide by the number of groups factorial is because choosing ABC DEF GHI is the same as DEF GHI ABC therefore we get 3! more arrangements. in the 2nd situation, there is an unequal number of people in each of the groups, therefore you dont need to divide by 3! as...

    Is it worth keeping Advanced in my case? (Ex-HSC marker teacher)

    Wow, most of the exemplars i see have like 7 single sided papers, your writing must've been full of quality
