What is the importance of having a long loop of Henle and short loop of Henle in a nephron?

Text Solution

Verified by Experts

The major function of Henle's loop is to concentrate `Na^+` and `Cl^(-)` . The longer the Henle's loop, the more concentrated is the urine that is above the osmotic concentration of plasma.

    a. Obtain an expression for the mutual inductance between a long straight wire and a square loop of side a as shown in the figure. b. Now assume that the straight wire carries a current of 50 A and the loop is moved to the right with a constant velocity, v=10m//s . Calculate the induced emf in the loop at the instant when x=0.2m . Take a=0.1m and assume that the loop has a large resistance.
