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.
