Lecture 20 Magnetic Field Field Lines Moving Chages Ppt 1) the document discusses magnetic fields, field lines, and the forces experienced by moving charges in magnetic fields. 2) it explains that a magnetic field extends through all space and is represented by magnetic field lines. a magnetic dipole field leaves the north pole and enters the south pole. 3) the magnetic force on a moving charge is. 20.1 magnetic fields, field lines, and force physics.

Lecture 20 Magnetic Field Field Lines Moving Chages 20.4 force on electric charge moving in a magnetic field the force on a moving charge is related to the force on a current: (20 3) • once again, the direction is given by a right hand rule (fbi). • maximum force occurs when the charge moves orthogonally to the field • the “current” direction depends on the charge carrier ( ). Moving charge: magnetic field lines. the magnetic field lines are circles centered on the line of v and lying in planes perpendicular to that line. direction of field line: right hand rule for charge point right thumb in direction of v. your fingers curl around the charge in direction of magnetic field lines. 2.

F = qvbsinθ f = q v b sin θ. 11.2. where θ is the angle between the velocity and the magnetic field. the si unit for magnetic field strength b is called the tesla (t) after the eccentric but brilliant inventor nikola tesla (1856–1943), where. 1t = 1n a ⋅ m. 1 t = 1 n a · m. The simplest case occurs when a charged particle moves perpendicular to a uniform b field, such as shown in figure 2. (if this takes place in a vacuum, the magnetic field is the dominant factor determining the motion.) here, the magnetic force supplies the centripetal force fc = mv2 r. noting that sin θ = 1, we see that f = qvb.
