#### Answer

Magnetic field is a vector. Magnetic flux is the scalar magnitude of magnetic field.

#### Work Step by Step

Magnetic field is a vector, and has units of tesla, T. Magnetic flux is proportional to the number of magnetic field lines passing through a closed loop, $\Phi_{B}=BA cos \theta$. It is a scalar, and has units of $T m^{2}$.
