Is magnetic flux scalar or vector
Magnetic flux is scalar, not vector. It is also scalar in college class
In the mathematical expression of magnetic flux, it is the scalar product (scalar product, dot product) of two vectors

- 2. 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
