Question

long, straight, vertical wire carries a current upward. Due east of this wire, in what direction does the magnetic field point? A long, straight, vertical wire carries a current upward. Due east of this wire, in what direction does the magnetic field point? north west south upward downward east

Answer 1

The correct answer to the question is;

North

Step-by-step 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.
