How do charged particles move in magnetic fields?
What can be deduced about the nature of a charged particle from observations of it moving in electric and magnetic fields?
the motion of a charged particle in a uniform electric field
the motion of a charged particle in a uniform magnetic field
the motion of a charged particle in perpendicularly orientated uniform electric and magnetic fields
the magnitude and direction of the force on a charge moving in a magnetic field as given by F = qvB sin θ
the magnitude and direction of the force on a current-carrying conductor in a magnetic field as given by F = BΙL sin θ
the magnetic field strength of an infinitely long current carrying wire
the force per unit length between parallel wires.
The kinetic energy of a charged particle stays constant in a magnetic field.
The determination of the charge to mass ratio for a charged particle by investigating its path in a uniform magnetic field is required.
The determination of the direction of the magnetic field based in the current direction in a current-carrying straight wire is required.
For parallel current carrying wires, the force is attractive when the current is flowing in the same direction.
