Question

Positively charged particles moving towards the west are deflected towards the north by a magnetic field. What will be the direction of the magnetic field?

Answer 1

Answer:

$\huge\mathcal\blue{UPWARD \: Direction}$

Explanation:

The positively charged particle is moving towards West that is, the direction of current is towards west ( current flows in the direction of the motion of positive charge) . The particle is deflected towards North , so the direction of force is towards North.

Thus Fleming's left hand rule , the direction of magnetic field is in upward direction.
