Hi. So, you surround a ferromagnet with a solenoid. Run current through solenoid to create B field withing. 2 Questions: 1:Why do the magnetic dipole moments in the ferromagnet "align" with the magnetic field of the solenoid? Doesn't lenz's law say that the magnetic field within the ferromagnet will "oppose" the introduced B field in the solenoid. 2:Consider a birds eye view of an electron orbiting a nucleus in the clockwise direction. Is the opposition of the Magnetic Dipole Moment (MDM) and the Angular Momentum vector of an atom/electron caused by the fact that L will point down due to the right hand rule and because convention says that MDM will point up because we use the CURRENT (flow of positive charge, not -ve) and the right hand rule, causing the MDM to point up? Cheers. Ollie.
