Question5 (5 points) A linear motor composed of conducting rod (the rotor) and permanent magnetic stator that provides a uniform magnetic flux density of 0.8 tesla in the shown direction. The rai...
As shown, a conducting rod moves
in the direction shown in a uniform magnetic
field directed into the page. Take the length of the
rod L to be 0.6 m, the magnetic field strength B to
be 0.55 T and the speed of the rod v to be 4.5 m/s.
a) What is the direction of the
magnetic force on electrons within the
conducting rod?
b) What are the magnitude and direction of the electric field in
the conducting rod?...
(a) Which part of an atom is positively charged, and which part is negatively charged? (b) How does the charge of an electron compare with the charge of another electron? (c) How does the charge of an electron compare with the charge of a proton? Can charge be created or destroyed? How does that answer relate to the conservation of charge? How is electric charge similar to mass? How are they different? What are two ways electric charge can be...
