An electron enters a region that contains a magnetic field directed into the page as shown. The velocity vector of the electron makes an angle of \( 30^{\circ} \) with the \( +y \) axis. What is the direction of the magnetic force on the electron when it enters the field?
(A) Up, out of the page
(B) At an angle of \( 30^{\circ} \) below the positive \( x \) axis
(C) At an angle of \( 30^{\circ} \) above the positive \( x \) axis
(D) At an angle of \( 60^{\circ} \) below the positive \( x \) axis
