A 10.6 kV/m electric field is used to inject a sample onto a 66.4 cm long capillary that has a diameter of 50 μm. The sample has an apparent mobility of 5.32×10−8 m2/(V⋅s) and a conductivity that is 1/15 of the conductivity of the buffer. How long must the electric field be applied to inject a sample that is 2.19% of the length of the capillary?

14-51 The solenoid used in an MRI scanner is 2 m long and 90 cm in diameter. It is wound froma copper wire 1.4 mm in diameter, with adjacent turns separated by an insulating layer of varnish with negligible thickness. See example 26.10 of your textbook. 4. Find the current that will produce a 0.5 Find the voltage that needs to be applied to generate this current. Resistivity of the copper is 1.75 x 10 m. Hint: find the length...
