Source of a Magnetic Field Current: moving charges induce magnetic fields Elementary Particles: have intrinsic magnetic fields around them which produce a permanent magnet Magneto A magnetic field is denoted by vector B it is given in Teslas: T = N C m s = N A · m Chapter 28: Magnetic Fields – p. Force on a Moving Charge Due to an electric field: vector F E = vector Eq Due to a magnetic field: vector F B = qvectorv × vector B The force vector F B acting on a charged particle mov- ing with velocity vectorv through a magnetic field vector B is always prependicular to both vectorv and vector B . Chapter 28: Magnetic Fields – p. Checkpoint #1 The figure shows three situations in which a charged particle with velocity vectorv travels through a uniform magnetic field vector B . In each situation, what is the direction of the magnetic force vector F B on the particle? Chapter 28: Magnetic Fields – p. Magnetic Field Lines Direction: Represented by the tangent to the field line at any point....
