velocity is moving towards the right, while the current runs perpendicular point

Question

velocity is moving towards the right, while the current runs perpendicular pointing down.

A proton is moving toward a wire that carries current in the direction shown.   a) What is the direction of the magnetic field produced at the proton by the current in the wire? b) What is the direction of the force on the proton? velocity is moving towards the right, while the current runs perpendicular pointing down.

A proton is moving toward a wire that carries current in the direction shown.   a) What is the direction of the magnetic field produced at the proton by the current in the wire? b) What is the direction of the force on the proton?

Explanation / Answer

1)direction of the magnetic field produced at the proton by the current in the wire is into the plane of paper as the direction of current is perpendicularly pointing down from Right hand rule . 2)F = qV*B (here V and B are velocity and magnetic field vectors and * is cross product ) direction of force is vertically upward .
