How Do You Solve These Electromagnetism Problems?

In summary, the conversation discusses different scenarios related to electrical and magnetic forces. These include finding the electrical force between two water molecules, calculating the Lorentz force exerted on an element by an infinite straight wire, determining the theoretical value of magnetization for nickel based on its electron configuration, and calculating the electromotive force induced on a dipstick when a current flows through a 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
