Question

A vertical wire carries a current straight up in a region where the magnetic field vector points toward the north. What is the direction of the magnetic force on this wire?

Answer 1

West

Step-by-step explanation:

The magnetic force is given by

F = i ( L × B)

This is in vector form

According to the question, the length is along +Z axis and magnetic field vector is along +Y axis.

So, by the right hand palm rule, the direction of force is along - x axis.

It means the force is towards west.
