I'm a high school student. We were taking Magnetic flux in school and the formula is $\Phi=BA\cosθ$.
Please Bear with me. My issue lies in the cosθ. I'm assuming here we treated the area as a vector but how can we treat the area as a vector? and how can the area decrease due to change in orientation?
I really want to understand the math behind it because if it is treated as a vector won't the area have two components? Again I'm not even sure if the area is even a vector. I'm not even sure what am I asking I'm just fed up with understanding physics it's too taxing
