Card 0 of 3
There is a particle with a charge of 
moving 
perpendicular through a magnetic field with a strength of 
. What is the force on the particle?
There is a particle with a charge of
The equation for force on a moving charged particle in a magnetic field is
.
Because the charge is moving perpendicularly through the magnetic field, we don't have to worry about the cross product, and the equation becomes simple multiplication.
Therefore, the force experienced by the particle is 3619N.

A conductive rod is moving through a region of magnetic field, directed out of the page as diagrammed above. As a result of its motion, the mobile charge in the rod separates, creating an electric potential across the length of the rod. The length of the rod is 0.12m and the magnitude of the magnetic field is 0.022T. If the rod is moving with velocity 
, what is the magnitude and direction of the potential from one end of the rod to the other?

For a conductor moving in a magnetic field, cutting straight across the field lines, a potential is generated 
where 
is the potential or EMF, 
is the magnetic field strength, and 
is the conductor's velocity relative to the field.
As the rod moves, the positive charge feels an upward-directed force by the right-hand rule, and the negative a downward force resulting in the top being at a higher potential than the bottom of the rod.

A conductive rod is moving through a region of magnetic field, as diagrammed above. As a result of its motion, mobile charge carriers in the conductor separate, creating an electric potential across the rod. When, if ever, do the charge carriers cease this motion?

The separated charge creates a potential 
. This potential results in an electric field 
When this induced electric field creates a force 
equal to the magnetic force 
on the mobile charge carriers, motion stops. Of course, if an electric circuit is created drawing current from the rod, motion will resume to rebuild the field.
