The magnetic flux through an area will be half of the max at 60degree.

[@danilahori4348]

Because cos 60 is 0.5 which is half of 1(cos 0)

Angle will be 60 degree... Magnetic flux will be maximum at angle 0 degree and Cos O is 1... So the half of maximum will be at 60 degree because Cos 60 is 1/2... . Is it correct?
