    Magnetic Flux is a scalar quantity.

    Magnetic flux is said to be a scalar quantity, yet it is measured bi-directionally, i.e. the direction in which direction the flux cuts the coil. In this case, is it just a simple scalar quantity or is it a vector (or something inbetween), as it has direction? the reason I am asking this is...
