When the charge is moving North (upward) down to a wire the field lines associated with this current will be inward on the right and outward on the left.
According to the Right Hand Thumb Rule the direction of the magnetic field associated with the current can be given as,
By pointing of the right hand into the direction of the current, the direction of the curling of the fingers of the right hand will give the direction of the magnetic field.
So, if the charges moving north which is upward direction,
The magnetic field lines associated with the current will be in a circular manner with the right side of the magnetic field Pointing inwards and the left side of the magnetic field Pointing outwards.
