SUMMARY

This discussion focuses on solving specific electromagnetism problems involving electrical force, Lorentz force, magnetization of nickel, and induced electromotive force. The first problem requires calculating the electric force of attraction between two water molecules using a dipolar bond equation. The second problem involves determining the Lorentz force exerted by a current-carrying wire on another wire. The third problem calculates the theoretical magnetization (M) for nickel, considering its electron configuration. Lastly, the fourth problem addresses the induced electromotive force on a duct rod moving parallel to a current-carrying cable.

1. Homework Statement
in the first one. I need to find the electrical force

in the second one. Lorentz force which exerts the wire on the other element

third. Magnetization (M) for Nickel

quarter. Electromotive force induced on the dipstick

Translate:

1.)If the power of a dipolar bond between two water molecules is represented by equation: (IMAGE) What is the electric force of attraction between the two molecules 2.)If a current (I) I2 = 3 A flows through the rectangle of the figure and through the infinite straight wire flows a current (I) I1 = 2, find the Lorentz force which exerts the wire on the other element 3.)Calculate the theoretical value of magnetization M for nickel (Z = 28), if two unpaired 3d electrons (d ^ 34s ^ 3) contribute to the magnetization. The nickel is FCC with a = 0.352 um as seen in the figure (IMAGE) 4.)A duct rod of length l = 20 cm moves parallel to a straight cable with a constant speed = 3 m / s, as in the figure. If a current I = 15 A flows through the cable, fiend the Electromotive force induced on the dipstick
