2. Describe magnetic forces due to moving charge (q) along a straight line and circle? Define 1 Tesla (T)? Calculate the diameter of the circular path of a moving charge (1.6 x10 -19 Coul) having mass of 9.1 x 10 -31 Kg, at a speed of 2 x 108 m/sec, placed in a magnetic field of 1 T? 3. Explain magnetic force on a current carrying conductor? How these concepts support you to calculate torque on a current loop? Find the maximum magnetic force act upon a conductor of length 0.3 m with current of 2000 A, when placed in a magnetic field of 0.2 Tesla? 4. Explain law of Biot and Savart? Also describe, how you can apply this law to a straight current carrying conductor? Calculate the distance from the current carrying conductor produce a magnetic field of 0.04 T, when 20 A current pass through it? 5. What is the force in between two parallel conductors? Why they attract each other? Explain Ampere's law? Find the magnetic field due to current of 1.3 A through a solenoid of length of 0.2 m and having number of coils 1000
