WebOne can immediately identify the direction of the magnetic field by looking at these signs. In terms of the direction, the cross (x) means out of the plane i.e. when an object is moving out of the plane and dot (.) means entering into a plane. This is the answer if u mean in terms of CURRENT’s direction.
