Only this will be helpful?
I have seen questions like why voltage is maximum when probe is parallel to magnetic field and stuff..
Thanks..

What should be the answer to Q5ciii
Check the syllabusDoes anyone has any notes on doppler effect
Do we have to do it for A2?
Explain why the alternating current in the primary coil of a transformer is not in phase with the alternating e.m.f. induced in the secondary coil.
There is a mistake in that part of question. So we are confused.Yeah but what if it were
What could have been the possible side...:/
No one solved my this doubt. I had the same doubt a month ago.I can't visualise this question
Which part of the needle is oscillating and how is it oscillating( which direction)? why is the amplitude 11mm? + in bi needle should be at its max height, i get it , but why is this max height 14mm below cloth or 8mm above cloth?
Can someone draw on the figure and explain
Please

Im also confused with this bs. I have not studied it anywhere that this happens but in marking scheme they have explained as if we know it.Because the current in the primary coil is in phase with the flux in the core <-------- How do we know this??
But not the change in the flux. <-------- change is flux wont be generated as we using ac?
So why does change in the flux not in hase with flux in the core.

http://papers.gceguide.com/A Levels/Physics (9702)/9702_s15_qp_42.pdftell me from which year and paper this is. i remember explaining this.
or give me the question itself
I dont understand that lines u have written.
