Question

Magnet wire is to be coated with varnish for insulation by drawing it through a circular die of 1.0 mm diameter. The wire diameter is 0.9 mm and it is centered in the die.The thicknesses are h1 5 0.5 mm and h2 5 0.3 mm, respectively. Find the force F to make the upper plate move at a speed of 1 m/s.What is the fluid velocity at the interface between the two fluids?

Answer 1

To determine the current flow through a 14-gauge copper wire based on its diameter (1.628 mm) and drift velocity (1.00 mm/s), Physics formulas concerning currents and charge carriers in a conductor must be applied using the physical properties of copper.

Step-by-step explanation:

The question is from the subject of Physics, specifically pertaining to electromagnetism and involves calculating the magnitude of current flowing through a wire given its diameter and drift velocity. According to the provided information, a 14-gauge copper wire has a given diameter of 1.628 mm. To find the current, we would need the cross-sectional area of the wire, the charge of an electron, and the number density of free electrons in copper. By using the formula for current (I = nAve), where n is the number density of free electrons, A is the cross-sectional area of the wire, v is the drift velocity, and e is the elementary charge, one can calculate the magnitude of current in the wire when the drift velocity is 1.00 mm/s.
