Case study : Read the following paragraph and answers the questions : The large-scale transmission and distribution of electrical energy over long distances is done with the use of transformers. The voltage output of the generator is stepped-up. It is then transmitted over long distances to an area sub-station near the consumers. There the voltage is stepped down. It is further stepped down at distributing sub-stations and utility poles before a power supply of 240 V reaches our homes. Which of the following statement is true?

Two linear parallel conductors carrying currents in the same direction attract each other and two linear parallel conductors carrying currents in opposite direction repel each other. The force acting per unit length due to currents I_1 and I_2 in two linear parallel conductors held distance r apart in vacuum in SI unit is F=(mu_0)/(4pi)(2I_1I_2)/(r) Read the above passage and answer the following questions: (i) What is the basic reason for the force between two linear parallel conductors carrying currents? (ii) Two straight wires A and B of lengths 2cm and 20cm , carrying currents 2*0A and 5*0A respectively in opposite directions are lying parallel to each other 4*0cm apart. The wire A is held near the middle of wire B. What is the force on 20cm long wire B? (iii) What does this study imply in day to day life?

A rectangular coil of n turns each of area A, carrying current I, when suspended in a uniform magnetic field B, experiences a torque tau=nIBAsin theta where theta is the angle with a normal drawn on the plane of coil makes with the direction of magnetic field. This torque tends to rotate the coil and bring it in equilibrium position. In stable equilibrium state, the resultant force on the coil is zero. The torque on coil is also zero and the coil has minimum potential energy. Read the above passage and answer the following questions: (i) In which position, a current carrying coil suspended in a uniform magnetic field experiences (a) minimum torque and (b) maximum torque? (ii) A circular coil of 200 turns, radius 5cm carries a current of 2*0A . It is suspended vertically in a uniform horizontal magnetic field of 0*20T , with the plane of the coil making an angle of 60^@ with the field lines. Calculate the magnitude of the torque that must be applied on it to prevent it from turning. (iii) What is the basic value displayed by the above study?
