# While operating, a high-precision TV monitor is placed on its side during maintenance. The image on the monitor changes color and blurs slightly. Discuss the possible relation of these effects to the Earth’s magnetic field.

The magnetic field of the earth can deflect electrons, affecting their usual movement and thus the monitor's performance.

See the step by step solution

## Step 1: Charged particle in the magnetic field

The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. In a magnetic field, a moving charge experiences a force that is perpendicular to both its velocity and the magnetic field.

## Step 2: Possible relation of these effects to the Earth’s magnetic field

A high-precision monitor is a delicate and accurate instrument that is greatly influenced by environmental factors. That means that something like the earth's magnetic field might impair its performance by deflecting electron movement, creating visual blurring or color overlapping.
