Are magnetic flux and magnetic field intensity vector or scalar respectively? Why?

Only physical quantities with size and no direction are called scalars, such as temperature, specific gravity, heat, energy, etc. while physical quantities with both direction and size are called vectors, such as velocity, acceleration, force, etc. so magnetic flux is only the amount of magnetic flux passing through, without direction, it must be scalar. Magnetic induction intensity and direction are all available, which can be seen from the definition! We also need to use the left-right rule to judge the direction!

11. Is work a vector or a scalar? Why According to w = flcosa Where f and L are all vectors, is the resulting w also a vector? Excuse me, if the right direction is defined as the positive direction, the object is still on the horizontal table, it is pulled 5 N horizontally to the left, and the object moves 5 m to the left, then the work done by the pulling force on the object is w = FS = 5 * - 5 = - 25J So, what force does is not negative work? And the pulling force is the motive force. According to the principle, we should do positive work. How to explain? Good answer, increase the reward
