Respuesta :

Answer:

The correct answer to the question is;

North

Explanation:

Fleming's left hand rule   states that the direction of a magnetic field acting on a current carrying conductor is perpendicular to both the force acting on the current carrying conductor and the direction of the current.

Therefore, since the direction of the current is upward and a force is acting with a direction towards the east of the wire then the direction of the magnetic field is northwards.
