TOPIC LEARNING OUTCOMES REMARKS HOUR5.2 Magnetic field produced bycurrent-carrying conductora) Determine the direction of magnetic field produced bycurrent-carrying conductor.b) Sketch the field lines produced by a long current-carryingconductor and by a circular wire.Use the 2 nd Right Hand Rule(corkscrew) to determine direction ofB r for both the long wire and circularwire.3c) Write and numerically determine the strength (intensity) ofthe field produced by a long wire as a function of the currentcarried by the wire and distance from the wire.μ0I‣ B = for a long straight2πrwired) Write and numerically determine the strength (intensity) ofthe field produced at the centre of a circular wire.e) Draw the magnetic field lines and label the North-South polesfor a solenoid.μ I‣ B = 0at the centre of a2rcircular wire of radius R.f) Write and numerically determine the strength (intensity) ofthe field produced along the centre of a solenoid.‣ B = μ0nIfor a solenoid withN turns per meter of the wire.Physics Lesson Outcomes-Electricity & Magnetismhttp://drjj.uitm.edu.my; HP:+60-19-355-1621Page 8 of 12Prepared by Assoc.
