February 25, 2009 PHY 2054 Discussion Spring ‘09 Conceptual Review: Chapter 19 1. A charged particle is moving in a uniform magnetic field. Under what condition is the force on the particle maximum? 2. Explain right-hand rule #1. B. Magnetic Force & Torque on current-carrying Conductors 1. A horizontal wire with mass m and length l carries current I and is in equilibrium without the force by supporting wires. What is the minimum magnetic field? 2. Does the magnetic torque depend on the shape on a loop or position of rotational axis? 3. What are the net magnetic force and torque on the double loop in the figure? D. Motion of Charges in Magnetic Fields 1. A charge is moving in a uniform magnetic field. If the velocity of a charge is increased, what happens to the radius and period of the circular motion? 2. What velocity should a charged particle have to pass in a velocity selector undeflected?
