Homework Answers
magnetic force is given by
F= q v×B
q is electric charge
v is velocity
B is magnetic field.
For 1st statement, magnetic force acts on moving charge as long as v is not along the same line as B
F is perpendicular to v as well as B

Suppose that a region with a uniform magnetic field B also has a uniform electric field E perpendicular to the magnetic field, an arrangement called crossed fields. Show that for a charged particle moving in such crossed fields in a direction perpendicular to both E and B, the electric force cancels the magnetic force, provided the particle has a speed v= E/B If the magnetic field is in the vertical upward direction and the electric field is in the northward...

Force on Moving Charges in a Magnetic Field
Magnets exert forces on other magnets even though they are separated by some distance. Usually the force on a magnet (or piece of magnetized matter) is pictured asthe interaction of that magnet with the magnetic field at its location (the field being generated by other magnets or currents). More fundamentally, theforce arises from the interaction of individual moving charges within a magnet with the local magnetic field. This force is written ,where is the force, is the individual charge (which...

A uniform magnetic field exists in a circular area. A particle carrying charge q = 8.0 mC is placed in the field a distance rp = 20 mm from the center of the circular area. If the particle experiences a force that has magnitude F = 4.00 μN and is perpendicular to the direction of the magnetic field, what is the magnitude of the rate at which the magnetic field is changing?
