magnetic force ppt

Magnets produce magnetic forces and have magnetic field lines. PowerPoint slide on Magnetism compiled by Hemkumar Mondal. The force around a magnet that attracts or repels. Gravity is created by mass and gravity acts on masses. At the poles of a magnet, the magnetic field lines are closer together. Electric and Magnetic Forces 29 F n 1 4 o qoqnurn r2 n, E(x) n 1 4 o qnurn r2 n. (3.3) 3.2 THE FIELD DESCRIPTION AND THE LORENTZ FORCE It is often necessary to calculate electromagnetic forces acting on a … to what they observe and why. 2. have two ends or poles, called north and south poles. Magnetic Force. So far we have studied two forces: gravity and electricity Magnetism is a new force, but also related to electric charges. Amazing Magnetic Force - Science Experiment! Presentation includes 9 slides with detailed speaker notes. - Longer version [11:06] with an explanation of what is happening after about 5 minutes. Region around a magnet in which magnetic forces can act. • 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. Force Due to a Magnetic Field on a Moving Charge •The force exerted on a moving charge by a magnetic field is given by •Where F is the force vector, q is the charge of the moving particle, v is the velocity vector of the moving particle, and B is the magnetic field vector. Electric fields are created by electric charges And Electric fields exert forces on charges. Currents and Magnets Exert Forces PPT [Includes “I Do”, “You Do”, and “We Do”] Currents and Magnets Exert Forces Notes the magnetic force dominates and relativistic electron beams can be self-confined. 10. The direction of force (motion) of a current carrying conductor in a magnetic field is given by Fleming’s Left Hand Rule.. – In electromagnets mmf is proportional to coil Shape is . Magnetic Circuits •Magnetic Flux in circuit similar to current – Unit: Maxwells (Mx) = 1 magnetic line of force. Keynote presentation about magnetic force and magnetic fields. Considers the following questions:-How are magnetic fields created?-What is a magnetic field?-How do magnetic fields interact?-What are magnetic … • Magnetic lines of force are closed curves. • The magnitude of the force is proportional to the current, I, the magnetic field magnitude, B, and the length L of the wire ttats te agetc edhat is in the magnetic field. Pete's PowerPoint Station is your destination for free PowerPoint presentations for kids and teachers about Magnets, Magnetism, Magnetic Fields, and so much more. r r kQ E ˆ 2 = v F E qE v v = Magnetic field and force Magnetic Force on Current • If a current is placed in a region of magneti fi ld it ill itic field, it will experience a magnetic force. Outside the magnet their direction is from north pole to south pole and inside the magnet these are from south to north pole. shown with lines drawn from the north pole of the magnet to the south pole, called . 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. magnetic field lines. ...
