a. A circular coil of wire carries 50 mA of current. The coil has 50 turns and an area of 2.0 cm². A magnetic field of 0.300 T is present, oriented parallel to the plane of the coil. What torque acts on the coil? b. Discuss the similarities and differences between the electrical force on a charge and the magnetic force on a charge. C. What is the basis of definition of current measuring unit 'ampere'? What are the relative advantages and disadvantages of Ampere's law and the law of Biot and Savart for practical calculations of magnetic fields? d. An alpha particle (+2e) travels in a circular path of radius 0.50 m in a region with a magnetic field whose magnitude is 0.10T. Find (a) the period, (b) the speed, and (c) the kinetic energy (in electron volts) of the alpha particle. (The mass of an alpha particle is 6.65×10-27 kg). e. A straight segment of a current-carrying wire has a current element IL where I =1.7A and L = 1.0 cm i + 5.0 cm ĵ. The segment is in a region with a uniform magnetic field given by 1.7 T î. Find the force on the segment of wire. a. A circular coil of wire carries 50 mA of current. The coil has 50 turns and an area of 2.0 cm².
