Question

A Hall effect experiment is set-up with a conducting strip placed inside a magnetic field. A voltmeter is used to measure the voltage in the direction perpendicular to the direction of the current through the strip, as shown in Fig. 27-7. A current I runs in the positive y-direction, while the magnetic field is oriented in the positive z-direction. If the reading of the voltmeter is positive when the wires are connected to its terminals as shown below, what is the sign of the charge carriers in this strip?

Explanation / Answer

negative sign
