How Hall Effect Magnetic Sensors Works [SOLVED]

[Carl Fredrik Ahl]

passing a continuous current through itself. When the device is placed within a magnetic field, the magnetic flux lines exert a force on the semiconductor material which deflects the charge carriers, electrons and holes, to either side of the semiconductor slab. 

 

I wonder why the semiconductor needs to send a current through itself in order for the protons and electrons (positive and negative charges) to get effected by the magnet and get to either side of the semiconductor. There are only negative charge in the current of course (cause it's all electrons, which should result in the electrons getting to one of the sides of the semiconductor, but how does it works with the protons (the positive charges)?

This is wrong.

Is this quoted from somewhere?

I don’t know a semiconductor can send a current “through itself” but static charges are not affected by a magnetic field. They only experience a force if they are moving. Hence a current is required. 

Note that your first sentence (quote?) is correct: the positive charges are holes, not protons.

Holes act as positive charge carriers in semiconductors.

Yeah I forgot that, I wrongly though of it as protons, thx for reminding me.

Why is this?

It's quated from this source: https://www.electronics-tutorials.ws/electromagnetism/hall-effect.html

Thx for the answers. I remember how it works now and I don't need help with explaining anymore. Since I cannot mark this post as "solved" I post this comment instead if that's ok.

Yes that's fine and thanks for letting us know. +1
