The direction of the magnetic force on the proton will be positive Z direction.
The magnetic influence on moving electric charges, electric currents,ch1 and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is moving through a magnetic field. ch13 : 278 The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts or repels other magnets. A magnetic field that varies with location will also exert a force on a variety of non-magnetic materials by changing the velocity of those particles' outer electrons. Electric currents, like those utilized in electromagnets, and electric fields that change in time produce magnetic fields that surround magnetized things.
Calculations:
Magnetic force on proton is,
[tex]F=q(v x B)\\v=-[/tex]lvl i
B= -lBl j
F= q(-lvl i x -lBl j)
F= q lvl lBl (-i x -j)
F=q lvl lBl k
F= lFl k
Direction of force will be positive Z direction.
