... If it were non-zero for some reason, charges would move within the conductor. The separation of positive and negative charge would set up an internal electric field which would oppose the original field. In equilibrium the two fields would be equal and opposite, making the total field zero. ...

... If we make the (positive) ion beam go through an area with an Electric field directed up and a Magnetic field directed out, then for the beam to NOT be deflected, we need qvB = qE, which gives v=E/B. If the incoming ions go too fast, the magnetic force “wins” and they go too low; if they go too slow ...

... Turn on the power supply and turn the voltage up until the current reads approximately 1.0 A. Adjust the sliding masses to re-balance the scale. Record the current and the mass. Repeat this 13 times with increments of approximately 0.5 A. CAUTION: The high power resistor may get hot. Avoid touching ...

Hall effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
