- The circuit shown in the given figure is a model of a solenoid, such as that used to engage the gear of a car’s starter motor to the engine’s flywheel. The solenoid is constructed by winding a wire around an iron core to make an electromagnet. The resistance R is that of the wire, and the inductance L is due to the electromagnetic effect. When the supply voltage vs is turned on, the resulting current activates the magnet, which moves the starter gear. Obtain the model of the current i given the supply voltage vs.arrow_forwardFaraday’s Lawarrow_forwardBoth the Biot-Savart and Coulomb's laws exhibit an inverse-square relationship between field and source.?

This basic model is used to understand chemical reactions, bonding, and other forms of atomic processes. It also shows you the strength of electrostatic forces in an atom. The Thomson model of a hydrogen atom is a sphere of positive charge with radius Ro with an electron (a point charge) at its center. The total positive charge equals the electronic charge q. What is the force of attraction between an electron at a distance R from the center of the sphere of positive charge?
