Calculate the magnitude and direction of the force exerted on a charged particle in terms of q, v, and B, and
explain why the magnetic force can perform no work.
Deduce the direction of a magnetic field from information about the forces experienced by charged particles
moving through a magnetic (B) field.
Describe the paths of charged particles moving in uniform magnetic fields.
Derive and apply the formula for the radius of the circular path of a charge that moves perpendicular to a
uniform magnetic field.
Describe under what conditions particles will move with constant velocity through crossed electric and
magnetic fields.
Calculate the magnitude and direction of the force on a straight segment of current carrying wire in a
uniform magnetic field.
Indicate the direction of magnetic forces on a current-carrying loop of wire in a magnetic field, and
determine how the loop will tend to rotate as a consequence of these forces.
Calculate the magnitude and direction of the torque experienced by a rectangular loop of wire carrying a
current in a magnetic field.
Calculate the magnitude and direction of the field at a point in the vicinity of a current carrying wire.
Use superposition to determine the magnetic field produced by two long wires.
Calculate the force of attraction or repulsion between two long current-carrying wires.
Calculate the flux of a uniform magnetic field through a loop of arbitrary orientation.
Recognize situations in which changing flux through a loop will cause an induced emf or current in the loop.
Calculate the magnitude and direction of the induced emf and current in a loop of wire or a conducting bar
under the following conditions: The magnitude of a related quantity such as magnetic field or area of the
loop is changing at a constant rate.
