Chapter 17: Magnetic Fields

Magnetic Field

A vector field caused by charges that determines the force felt by other charges.

Magnetic Field

Force exerted on point charge by magnetic field

Net force on a point charge due to electric and magnetic fields

straight line

Charged particles moving parallel to the magnetic field experience no force and therefore move in a \_____.

The strength of the field determines the radius of this motion according to the following equation that sets the magnetic force equal to the centripetal force

net effect

The \_____ is a helical path through space, with the axis of the corkscrew parallel to the magnetic field.

Force on a straight current-carrying wire in a constant magnetic field

Force on a differential length dl of current-carrying wire in a magnetic field

net force on a wire of arbitrary shape

Mass Spectrometer

A device that measures the mass/charge ratio of charged atoms and molecules.

Energy gained by passing through a capacitor converted to KE

Electric field in a parallel plate capacitor

Magnetic field due to a point charge

Biot-Savart law

Definition of Magnetic field in Vector

Biot-Savart law

magnetic field due to a differential length of wire

Magnetic field due to an infinitely long current-carrying wire (direction given by the right-hand rule)

Force per unit length on each of two parallel current-carrying wires

force on wire 1 per unit

Ampere’s law
