1. Refer to figure 1. A moving charge passes through and perpendicular to a magnetic
field. Calculate the magnitude of the force the charge will experience and the direction
it will travel.
2. How much force will the charge experience if it were to come in at a 30.0° angle to the
magnetic field?
Figure 1: A 0.020 C charge travels
initially perpendicular to a 0.025 T
magnetic field at 12.0 m/s.

1. Refer to figure 1. A “roundish” loop that is 5.0 cm x 5.0 cm ca
ies a cu
ent of 0.25 A
and rotates about its axis in a magnetic field of 0.125 T. Calculate the magnetic
moment and the torque the loop experiences.
2. How much torque will the loop experience if you reorient the magnetic field to 60° with
espect to the loop?
