What you learn in Theory:
Magnetic field can vary with time. Principle of superposition can be applied to it. Its a vector quantity.
What you learn in Practice:
magnetic field is quite similar to electric field. Both are vector. Both can be due to multiple charges. only difference is electric field is due to the static charges and magnetic field is due to the moving charges.
