a positively charged particle projected towards west is deflected towards north then the magnetic field is

Expert Answer:

Since the positively charged particle is projected towards west, so the direction of current is towards west. Now the deflection is towards north, so the force is towards north.
According to Fleming's Left Hand Rule, if centre finger points in the direction of current (west), thumb points in the direction of force (north), then forefinger points in the direction of magnetic field (upwards). Thus, the magnetic field is in upward direction.
