Rotating conductor in magnetic field

[jsmit21]

Homework Statement

The problem consists of a single rotating conductor in a magnetic field as shown, I don't understand at which given numbered points where there would be a maximum and zero induced emf ?

The Attempt at a Solution

I know that its said to be when the conductor is parallel with the magnetic field it is cutting no flux lines and therefore no emf is induced and when it is cutting at 90° perpendicular to the field the emf is maximum, so I am guessing that at position 1 it would be maximum, but I'm not sure.

Welcome to the PF.

You deleted the part of the Homework Help Template that asks for the Relevant Equations. What is the equation that is most relevant to this problem? That is what you will use to answer the question...

Thanks for your reply, is it the case then that if V=BLVSinθ, then at position 1, since the angle is 90° to the lines of flux it would be maximum, i think I'm confused about statements of coils being parallel being 0, and perpendicular being maximum any help is appreciated ?

That's not the equation I was thinking of. There is an equation that relates the voltage induced around the periphery of a surface to the derivative of the flux piercing the surface...
