20.5b Ex3 ON06 P4 Q5 Eddy Current Pendulum & Braking | A2 Induction | CAIE A Level 9702 Physics
Example 3 - 9702/4/O/N/06: A metal disc is swinging freely between the poles of an electromagnet, as shown in Fig. 5.1. When the electromagnet is switched on, the disc comes to rest after a few oscillations.
#9702w06p4 #Lv3 #A2eddyCurrentsP4 #A2movingConductorsP4
(a) (i)State Faraday’s law of electromagnetic induction and use the law to explain why an e.m.f. is induced in the disc (ii)Explain why eddy currents are induced in the metal disc
(b)Use energy principles to explain why the disc comes to rest after a few oscillations

hello , I love your channel ! you guys explain the concept so well and I understand it really easily ( seriously thank you so much ) do you mind uploading some videos about the communication chapter ? I'm really lost about that ahhh, it would help a lot !!

I'm glad you're learning more about physics! Communication is last on the queue, so that'll be somewhere end of March. :)
Luv ur channel !!!!!
u saved my life
life saver, thank you so much omg

Hey do you know if eddy currents is removed from a level physics cie? Can't find it on their 2022 syllabus
this topic(eddy currents) is out of the 2022 syllabus, right?
Is eddy currents in our syllabus?
