1. Describe magnetic forces due to moving charge (q) along a straight line and circle, with details of formula and figure? Define 1 Tesla (T)?

Problem-1: Find the force act upon a moving charge (50 C) at a speed of 15 mm/sec in a magnetic field of 0.5 T? ( = 90).

2. Explain torque on a current loop? Describe the working principle of DC motor. Draw the figure and explain?

Problem-2: Calculate torque produced due to a rectangular loop (N = 3000, Size: 14 cm X 10 cm) carrying current 5 A, placed in a magnetic field of 1.5 T? ( =90)

3. Explain law of Biot and Savart? Also describe, how you can apply this law to a straight current carrying conductor?

Problem-3: Calculate the distance from the current carrying conductor produce a magnetic field of 0.06 T, when 600 A current pass through it?
