- Describe one way in which an electric dipole and a permanently magnetized bar magnet exhibit similar behaviors or properties. Then describe another way in which they exhibit clearly different behaviours or properties8. * The B field in a region has a magnitude of 0.40 T and points in the positive z-direction, as shown in Figure P21.8.

A mass spectrometer is being used to separate common oxygen-16 from the much rarer oxygen-18, taken from a sample of old glacial ice. (The relative abundance of these oxygen isotopes is related to climatic temperature at the time the ice was deposited.) m The ratio of the masses of these two isotopes is 16 to 18, the mass of oxygen-16 is 2.66-10-26 kg, and they are singly charged and travel at 5.5.106 in a 1.25 T magnetic field.
