If we were to analyze the magnetic flux lines of a current-carrying conductor, oriented perpendicularly to a magnetic field between two bar magnets, the interaction would look something like this: S N S N This interaction of magnetic flux lines (the bar magnets' straight lines versus the wire's cireles) will produce a mechanical force on the wire (called the Lorentz force). Which direction will this force act? Also, determine the direction of current through the conductor (seen from an end-view in the above illustration) necessary to produce the circular magnetic flux shown.
Consider a region where the electric field and the magnetic field are along the +x- and the -y-axes, respectively. If a certain charge is in the region, at what velocity should it move so that it will move in a uniform velocity? (To maintain a uniform velocity, the Lorentz force must be zero) Let E and B be the magnitudes of the electric field and of the magnetic field, respectively. B V = - - B E az V = E V = az 1>
A distant galaxy is observed with a spectrometer. This galaxy produces an emission line that is identified as a Hydrogen transition that normally has a wavelength of 21 cm. For this galaxy, however, the emission line is observed at a wavelength of 33 cm. How fast is this galaxy moving away from us in units of km/s [round off your answer to 1 km/s]
