Q2. a) An aluminum wire of length 10 m and having a cross sectional area 1.52x104 m is converted into 2-turn circular and is connected to a voltage of 0.115 V. If the loop is placed in, a uniform magnetic field of magnitude 0.86 T at an angle of 72, then calculate the torque produced in the loop? (The resistivity (p) of Aluminum is 2.82x10-8 2.m.) b) If the circular loop is changed into a square shaped loop with 3 number of turns but all other same values, then which loop will have less torque? Show calculation. (1.5+1=2.5 Marks)
