HALL PROBE

(1/3) > >>

Gaz:
Anyone know what a hall probe is and how it is to be used? It can turn up in Physics Paper 5.

Meticulous:
A hall probe is a device that is used to measure the magnetic flux density (B) of a magnetic field, either of a magnet (placed perpendicularly to field lines)

or that of current in a conductor.

So it gives a reading in tesla? And any past papers where it has been used?

Meticulous:
Yes. It is connected to a data logger and a computer, and it gives the reading in Tesla.

I do Edexcel, and I have it in past papers. I dont think CIE does.

ah ok thanks. could you link me to a few edexcel past papers that do? and the cie physics syllabus does state that candidates should be able to use one.
