Question

An electromagnetic flowmeter can measure the speed of blood flow through an artery during
surgery. When the meter is turned on, positively- and negatively-charged ions in the blood
tend to accumulate near opposite walls of the artery (as shown in the diagram below). This
causes an electric field within the artery.

(a) Sketch the electric field set up by the grouping of ions.
(b) What is the magnitude of the force on an ion, with charge of *q, flowing along the
middle of the artery, due to the electric field within the artery? Express your
answer in relation to the magnitude of the electric field.
(c) What is the direction of this force?
(d) Repeat for charge of q (equal in magnitude but opposite in sign.)

Expert Solution

Step 1

Electro Magnetic Flowmeter -- The electromagnetic flowmeter are devices by which the voltage signal determines liquid flow. Electromagnetic flowmeter or mag flow meters are incredibly useful devices for controlling precision dosing operations and flow measurement applications.
