Question
An electron is moving along positive x-axis in a magnetic field which is parallel tothe positive y-axis. In what direction will the magnetic force be acting on theelectron
Solution 1
The direction of the magnetic force acting on the electron can be determined using the right-hand rule.
- Point your right thumb in the direction of the electron's motion (along the positive x-axis).
- Then, point your right index finger in the direction of the magnetic field (along the positive y-axis).
- Your middle finger will then point in the direction of the force.
However, because we are dealing with an electron, which is a negatively charged particle, the force will be in the opposite direction to what your right hand indicates.
So, the magnetic force will be acting in the negative z-direction.
Solution 2
The direction of the magnetic force acting on the electron can be determined using the right-hand rule. However, since electrons have a negative charge, we use the left-hand rule instead.
Here's how you apply the left-hand rule:
- Point your thumb in the direction of the electron's movement, which is along the positive x-axis.
- Point your index finger in the direction of the magnetic field, which is along the positive y-axis.
- Your middle finger will then point in the direction of the force.
So, the magnetic force will be acting in the negative z-direction.
