ABcos(theata) cant find symbol for that.

the question asked you to find magnetic flux I have worked out A and B but Im unsure what it means when it says : the angle is 66 degrees below the horizontal:

Thanks

(have a theta: θ and a degree: º )

(i still don't understand what this is about )

I assume that θ is the angle between A and B,

so what are A and B?

Determine the magnitude of flux of the earths magnetic field through a wedding ring of diameter 2.2cm when the ring is held in the horizontal plane.

What is the magnitude of flux change when the ring is flipped through 180 degrees.

It the angle that is bothering me

Thanks

so

ok, the flux through a surface (or through its boundary) is greatest when the surface is perpendicular to the field, ie when the normal to the surface is parallel to the field.

So θ is the angle between

I see so I would be using cos24 not cos66
