That one's a gray area, if from B or flux graph we can tell a clear, sudden change in gradient, then emf will be sharp. But in real life, it will be more like a spike!
Its only cos if the angle is made between the B-field lines and a the A vector perpendicular to the plane. It’s sin if it’s the angle made between the plane and the B-field lines. In this case it’s the second scenario.
honestly u the best ever!!!
But why sin seta not cos?
12:48 how does the right hand grip rule fit here?
Hi, for the graph of induced emf, I see questions drawing a spike rather than a rectangle, why is that so?

@@ETphysics ohh okayy thankss!!
Is right hand grip rule in the syllabus
Its NBAcos(tita) not sin
Yeah that's what I thought it's definitely cos right?

Many t;hanks for the video 3
we take the vector component that is NINETY degree to the plane of the coil. look at where the angle is defined in the drawing :)
