Copper in a Magnetic Field

A strip of copper is placed in a uniform magnetic field of magnitude \({{params.B}}\textrm{ T}\). The Hall electric field is measured to be \({{params.E}} \times 10^{-3}\textrm{ V/m}\).

Part 1

What is the drift speed of the conduction electrons?

Answer Section

Please enter a numeric value.

Part 2

Assuming that \(n = {{params.n}} \times 10^{28}\) electrons per cubic meter and that the cross-sectional area of the strip is \({{params.A}} \times 10^{-6} \rm\ { m^{2}}\), calculate the current in the strip.

Answer Section

Please enter a numeric value.
