in magnetic flux-magnetic flux density,why we use cos only why not other trignometric ratios?
Answers
Answer:
BECAUSE VERTICAL COMPONENT SIN CANCEL TO EACH OTHER BCZ OF EQUAL AND OPPOSITE MAGNITUDE
Answer:
Ohk a really nice question.
Well, if you're aware of the fact that the formula for any of these quantities be it Magnetic flux, or Work done due to a force all have this cos multiplied in their formula.
The formula actually for Magnetic flux is given as
Flux = Magnetic Field Vector dot Area vector
And, so it is this vector operator dot which actually produces a cosine term multiplied to the product of the magnitude of each of these quantities at the same instant.
Actually, geometrically intuitively this dot product also called the scalar product gives the projection length of one of the vector onto another vector.
Hope this helps you !
You'll learn about these in much deep aspects in higher classes , about vectors in which you also have the cross products and so on.
