9702/52/M/J/14: Two identical coils are connected together and arranged as shown in Fig. 1.1. The coils are in the vertical plane and are parallel to each other. When the coils are connected to a power supply, there is a magnetic field between them. #A2physicsP5 #A2magnetsP5Q1
It is suggested that the magnetic flux density B of the field at the point X is related to the radius r of the coils by the relationship B = 0.72μ0NI/r where N is the number of turns on each coil, I is the current in the coils and μ0 is thee permeability of free space. Design a laboratory experiment that uses a Hall probe to test the relationship between B and r and determine a value for μ0.

Fun fact you saved me from failing as and now you're saving me from failing a2.Thank you so much.
I wheezed when you said ghosts holding the experiment😂
so many ghosts in the lab
Thank you so much!! I have a question, for paper 5, when do we need to use a.c power supply? Example of experiment?
Whenever there is an induced current. You are probably done with your a2 by now 💀💀. I have my exam in 2 days lol.
@@mashriqafnan2372 I have it tomorrow well its 1 pm already so yeah todaay
@@ROSLYNNNN same man best of luck
@@mashriqafnan2372 Thank you soo much please give me some tips 😭 I neglected p5 and now I am regretting
@ROSLYNNNN Dw man just do Q:2 first then Q: 1. My exam is in two hours 😭😭
I would love a ghost helping me out with the experiment.
a bit late but in the additional details its mentioned a "method to check coils are parallel". so what exactly would that method be?
clamp the coils as shown 8:53
@@JiwonLee-kn9ptwon't that mess with the magnetic field?
Can you do winter 11, p51
Can't understand a damn thing
no because paper 5 physics is just a waste of our grades,literally nothing makes sense🤧
@@media9755 only Q2 is easy
P5 is very stupid but tbh it's easy bcs u can just make everything up
@@aleena158 but u don't get marks for everything
@@aleena158 I have p5 tmrrw 🙃
