Question

Why do we heat the copper in the hall effect experiment?

How does temperature affect the hall effect?

How does temperature affect the hall coefficient?

Why is temperature relevant in the hall effect experiment?

Why do we have a thermocouple in the hall effect experiment?

Answer 1

we wish to measure effect of temperature over hall voltage, so we heat copper to a specific temeprature to read the characteristics

an increase in temeprature increases the resistance of the object there by, decreasing the hall voltage

Hall coefficient remains constant with temperature as number density remains constant with temperaure and hall coefficent = 1/ne

as due to current voltage dfeveloping on on the transverse direction of conductor, and the charges movingin oppsote direction as well, the conductor is bound to get warm, so it is worthwile to know effects of temperature already on the hall voltage

the thermo couple stops feeding the current for warming the copper plate when it reaches a specific temperature, and this ensures we have right temperature readings for study of effect of temeprature in hall effect
