For the particle to move anti-clockwise- force should be in -j direction-x2192-F-x2212-e-x2192-v-xD7-x2192-B-x2212-e-v-i-xD7-x2192-B-x21D2-x2192-B-B-k since LHS is in -j direction-

An electron is moving along positive $x -$ axis. To get it moving on an anticlockwise circular path in $x - y$ plane, a magnetic field is applied
along positive $y -$ axis
along positive $z -$ axis
along negative $y -$ axis
along negative $z -$ axis

For the particle to move anti-clockwise, force should be in $^j$ direction.

$\to F = - e (\to v \times \to B) = - e (v^i \times \to B)$

$\Rightarrow \to B = B^k$ since LHS is in $^j$ direction.

An electron is moving along positive x−axis. To get it moving on an anticlockwise circular path in x−y plane, a magnetic field is appliedalong positive y−axisalong positive z−axisalong negative y−axisalong negative z−axis

For the particle to move anti-clockwise, force should be in ^j direction.→F=−e(→v×→B)=−e(v^i×→B)⇒→B=B^k since LHS is in ^j direction.
