TOPIC LEARNING OUTCOMES REMARKS HOUR5.3 Magnetic Force on amoving charged particleand on a current-carryingconductor.a) Determine the magnitude and direction of force acting on acharged particle moving near a current-carrying conductor.b) Determine the magnitude and direction of the force actingbetween two parallel current-carrying conductors andbetween two wires carrying current in opposite directions.c) Determine the direction of the force acting between twoparallel circular wires carrying current in the same directionsand two parallel circular wires carrying current in theopposite directions.d) Compute the force per unit length on two adjacent parallelcurrent-carrying conductors‣ Use the 1 st Right Hand Rule.F = qvBsinθ‣ Force between two parallelwires:F = qvBsin θvB= ILBsinθIB.You need to first determine theB field produced by each wire(using the corkscrew rule) beforeapplying the 1 st Right HandRule.‣ Determine the poles for thecircular wires beforedetermining the direction offorces between two parallelcoils.‣ Assume wires of same lengths L,F μ0I2then = I1 B = I1L 2πdvB35.4 Torque on a coil a) Determine the force directions on the sides of a rectangularcoil with surface area A and carrying current I placed in amagnetic field B.b) Describe the effect of the magnetic force on the coil,qualitatively and pictorially.c) List and explain the factors affecting speed of rotation for arectangular coil of surface area A, carrying current I placed ina magnetic field B.‣ Use results from section 13.3‣ Show the force directions andthe direction of rotation for bothsides and how that changes whencurrent direction or fielddirection is reversed.‣ Area, field strength, number ofturns and the current26.0 ELECTROMAGNETICINDUCTIONAt the end of this topic, the student will be able to: 4Physics Lesson Outcomes-Electricity & Magnetismhttp://drjj.uitm.edu.my; HP:+60-19-355-1621Page 9 of 12Prepared by Assoc.
