What is the direction and magnitude of the magnetic field the particle is traveling? What is the direction and magnitude of the magnetic field the second particle is traveling?
A 9.9 x 10^-5C charged particle is traveling east, with speed 4.0 x 10^5 m/s. The particle feels a force of 0.24 N going south, due to a large bar magnet. A second particle of charge 2.7 x 10^-4C is traveling upward, with speed 2.0 x 105 m/s. The particle feels a force of 0.26 N going south, due to a large bar magnet.

Explanation:
The force
These 3 vectors of magnetic field
Imagine rotating the above diagram by
You can see that a +ve charge moving from left to right across the screen (east) will feel a force vertically downwards (south) if the direction of the field
The 2nd part of the question does not make sense to me. The force must be perpendicular to the motion and not in an opposite direction, as described in the question.
