magnetic force powerpoint
Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. PowerPoint slide on Magnetism compiled by Hemkumar Mondal. magnetic field lines. 2. have two ends or poles, called north and south poles. Shape is . hand rule) net magnetic force on nail is attractive (a) or (b) unmagnetized Fe object is attracted to either pole of magnet. Magnetic Force on a Current- Carrying Conductor• If a straight conductor of length ℓ carries current, the magnetic force on that conductor when it is placed in a uniform external magnetic field B is: F = BIℓ sin θ• Where Ɵ is the angle between the direction of the current and the direction of the magnetic field. • Magnetomotive Force (mmf) similar to voltage – Unit: Gilberts (Gb) = the mmf that will establish a flux of 1 Mx in a magnetic circuit having a reluctance (rel) of 1 unit. The magnetic force between magnets depends on how the poles of the magnets line up. Magnetic Field Magnetic Pole North Pole South Pole Magnetic Field Line Domains The resources below are set up in a model lesson format. Magnetic Circuits •Magnetic Flux in circuit similar to current – Unit: Maxwells (Mx) = 1 magnetic line of force. shown with lines drawn from the north pole of the magnet to the south pole, called . Region around a magnet in which magnetic forces can act. The direction of force (motion) of a current carrying conductor in a magnetic field is given by Fleming’s Left Hand Rule.. Like poles repel, and opposite . CrystalGraphics brings you the world's biggest & best collection of magnetic force PowerPoint templates. – In electromagnets mmf is proportional to coil Magnetic Force. S N N S. Title: Microsoft PowerPoint - Chap27_PHY2049.ppt Author: Beatriz Created Date: ... PowerPoint Presentation Last modified by: Keynote presentation about magnetic force and magnetic fields. The ppt provides guidance for the entire lesson including activating, teaching and summarizing strategies. The force around a magnet that attracts or repels. Standing Ovation Award: "Best PowerPoint Templates" - Download your favorites today! At the poles of a magnet, the magnetic field lines are closer together. Magnetism PowerPoint … WINNER! The direction of the magnetic force on the particle is: a) Right b) Left c) Into the screen d) Out of the screen e) Zero The magnetic force is given by The cross product of the velocity with the magnetic field is to the left and since the charge is positive the force is then to the left Three points are arranged in a uniform magnetic field. Magnets produce magnetic forces and have magnetic field lines. The activities listed below the ppt are used during the lesson and are identified in the ppt for This website and its content is subject to our Terms and Conditions. poles attract. Presentation includes 9 slides with detailed speaker notes. Tes Global Ltd is registered in England (Company No 02017289) with its registered office … Considers the following questions:-How are magnetic fields created?-What is a magnetic field?-How do magnetic fields interact?-What are magnetic …
