Hall probes

When does the Hall effect occur?

When a current-carrying conductor is placed in a magnetic field that is perpendicular to the current

What happens during the Hall effect?

Charge carriers move through the conductor. The magnetic field causes a force on the charges. The charges accumulate on one side. This creates a potential difference called the Hall voltage. Electronics convert the voltage to magnetic flux density. The display shows magnetic flux density

What are 4 advantages of Hall probes?

They measure very small fields. They give instant readings. They measure fields inside solenoids. They work where iron filings cannot

What are 4 limitations?

Incorrect orientation gives wrong readings. Temperature changes affect sensitivity. They need calibration. Electrical noise can affect output
