A magnetic field is applied to a freely floating uniform iron sphere with radius R = 2.00 mm. The sphere initially had no net magnetic moment, but the field aligns 12% of the magnetic moments of the atoms (that is, 12% of the magnetic moments of the loosely bound electrons in the sphere, with one such electron per atom). The magnetic moment of those aligned electrons is the sphere’s intrinsic magnetic moment .What is the sphere’s resulting angular speed v?
In a deuterium nucleus, the proton and neutron spins can be
either parallel or antiparallel. What are the possible values of
the total spin of the deuterium nucleus? (It is not necessary
to consider any orbital angular momentum.) The magnetic
dipole moment of the deuterium nucleus is measured to be
nonzero. Which of the possible spins is eliminated by this
measured value?

- Chapter 29: Magnetic Fields We studied how a moving charge would react in a magnetic field, which extends naturally to current where charges drift (hence moves) in a magnetic field. One special case of this is the torque due to current loops in magnetic fields: 7= μx B= IAX B since we defined the magnetic moment of a current loop as μ = IĀ. estimate the current that an electric car would have to provide to its motor such that it can do 0-100 kph in 3 seconds. Some useful hints for guidance are below: (1) . Find the acceleration using kinematics With the acceleration, what would be the torque needed for the motor to apply to the wheel? You need to estimate yourself the size of the wheel, as well as the size of the motor hub that is connected to the wheel.
