IV. Magnetic Force on Current-carrying Conductors A horizontal rod 0.25 m long is mounted on a balance and carries a current. At the location of the rod a uniform horizontal magnetic field has magnitude 0.05 T and direction perpendicular to the rod. The magnetic force on the rod is measured by the balance and is found to be 0.15 N. What is the current?

Answer #4 with diagram
1. Magnetic Force on a Moving Charge
A particle with a charge of -1.602 x 109 C is moving with instantaneous velocity i =
(1.5 x 10*)i+ (-4x 10* j. What is the force exerted on this particle by a magnetic
field B = (1.50 T)i +(-37)?
I.
Magnetic Flux
A circular area with a radius of 5 cm lies in the xy-plane. What is the magnitude of the
magnetic flux through this circle due to a uniform magnetic field B = 0.300 T in the +z-
direction?
I.
Motion of Charged Particles in Magnetic Field
A singly charged ion of 7Li (an isotope of Lithium) has a mass of 1.16 x 10 kg. It is
accelerated through a potential difference of 230 V and then enters a magnetic field with
magnitude 0.725 T perpendicular to the path of the ion. What is the radius of the ion's path
in the magnetic field?
