Q.1 (a) A filament loop that will carry current I is to be bent and take the form of a regular polygon with all sides having the same length. Angle from the centre of any regular polygon to one of its side is given as 2n/n as shown in Figure Q.1(a) where n is the number of sides that the polygon has. The radius of circle circumscribing the polygon is r. Using Biot – Savart's Law, determine magnetic field intensity, H at the centre of the polygon-loop to be designed with respect to n.

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.)
