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 mainly to clear up questions on graphs of "the amount of flux through the coil" on whether they should be |sin(x)| or just sin(x) which is the usually the correct one.

This misconception is common.
Scalars can be both positive and negative. These are called 'signed' scalars. Basically, a scalar is something which can be represented by a single number.
Energy is a scalar and can also be negative, same as work.

Magnetic flux is an example of what is called a 'dot product' in vector calculus, which is a scalar product.

thanks for clearing that up :)
