- A cylindrical solenoid 49 cm long with a radius of 7 mm has 325 tightly-wound turns of wire uniformly distributed along its length (see the figure). Around the middle of the solenoid is a two-turn rectangular loop 3 cm by 2 cm made of resistive wire having a resistance of 135 ohms. One microsecond after connecting the loose wire to the battery to form a series circuit with the battery and a 20 resistor, what is the magnitude of the current in the rectangular loop and its direction (clockwise or counter-clockwise in the diagram)? (The battery has an emf of 9 V.)This is a toroidal inductance. Calculate the inductance of this material. r1 = 96mm, r2 = 120mm, a = 10mm, I= 5A and N = 200 turns. Take 1200 the maximum relative permeability of the material. N turnsI. IDENTIFICATION. 1. It is composed of several connected members that are either fixed or pin connected at their ends. 2. The internal force Q in the direction of the centroidal axis of the beam is called the 3. The internal force V in the direction perpendicular to the centroidal axis is referred to as the 4. If the deformations disappear and the structure regains its original shape when the actions causing the deformations are removed, the deformations are termed 5. The permanent deformations of structures are referred to as
