From Lorentz force Equation we know that total force #vec F# experienced by a charged particle, having charge #q# and velocity #vec v#, in an electric field #vecE# and magnetic field #vecB# is

#vecF=q(vecE+vecvxxvecB)#

In this case, the electron of charge #e# is stationary in a magnetic field. There is no electric field. As such first term vanishes.
Also we have #vecv=0#. Consequently the cross product of vectors velocity and magnetic field becomes #0#.
We have
#vecF=e(0xxvecB)#
#vecF=0.#

In the absence of any force stationary electron remains stationary.
