AI Thread Summary
To calibrate a Hall probe, a known magnetic field strength (B) must be generated, typically using an electromagnet or solenoid. The relationship between the magnetic field and measurable currents can be described by the equation B = μ₀(nI), where μ₀ is the permeability of free space, n is the number of turns per unit length, and I is the current. Users seek methods to accurately measure and confirm the value of B during calibration. Discussions highlight the importance of precise current control and the use of reference materials or tools for verification. Accurate calibration is essential for reliable magnetic field measurements.

to calibrate a hall probe, i know we have to generate a known magnetic filed strength (B)...but how??

Is there an equation relating the "B" with measurable currents, etc?

Thanks for helping guyz!

so do i use a electromagnet (solenoid) n get current thru it to generate a magnetic field?
but i dun get how i cud know the exact value of B

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
