Flux = zero, minimum, maximum? (1 Viewer)

[dolbinau]

For a coil of wire in a magnetic field (i.e a motor)

Is there minimum flux through the coil when it is flat in the field

zero flux when the coil is perpendicular to the field

maximum flux when the coil returns back in the field?

Or is it zero initially as zero and minimum are the same? (I didn't think it was)

But this is confusing. Help!!

THanks

 

[adnan91]

Flux = magnetic field x area

@ = B x A

Greater the area greater the flux

So yes perpindicular= greatest flux

 

[dolbinau]

Also, when is there greatest change in flux? (What positions)

 

[lost1]

Greatest change in flux when parallel to magnetic field...basically, flux = BASin@ (@=angle between plane of coil and magnetic field) therefore change in flux is the derivative (rate of change if you do maths) df/dt = BACos@ (where f=flux )

Thanks, that's helpful .
