## Homework Statement

A magnetic field of 0.0200 T [up] is created in a region

Find the initial magnetic force on an electron initially moving at 5.00 X 10^6 m/s [N] in the field.

## Homework Equations

Work clarification and I would like to ask a question in relation to the direction of FM.

## The Attempt at a Solution

My answer,

FM=(1.6*10^(-19) C)(5.00*10^6 m/s)(0.0200 T)

FM=1.6 x 10^-14 N

Since it is an ELECTRON, it would alter the direction of velocity, changing it from NORTH to SOUTH . With that said, Magnetic field is [UP], Velocity is [SOUTH] and FM is [WEST]. Therefore my final answer is FM=1.6 x 10^-14 N [WEST].[Is my answer right?]I'm unsure of my answer (Above.) as I was told from 2 of my classmates that I did it wrong. They said that an ELECTRON changes both Velocity's and Magnetic field's direction. However, I looked at the examples my teacher did and he only changed Velocity's direction.So I was just wondering who's approach is right, my friends or mine?
