Suppose a charged particle of charge q moves through a distance l , with a speed v , in a direction that is perpendicular to a uniform magnetic field of strength B .
a. What will the time it takes for the particle to travel the distance l be?
b. What is the current caused by the moving charged particle?
c. Since this current occurs over a length l , show that the force on the moving charged particle in the magnetic field is given by F=Bqv .
d. Now suppose that the charged particle moves at an angle, θ , to the magnetic field. How will the equation for the magnetic force it experiences differ from that given in part c?
