If the radius of the coils is 50 cm, what would be the (peak) magnetic field at the center of a single coil loop?  (Show work.)

Use the concept of electromagnetic induction to explain why the light bulbs in the chandelier light up.  Recall that they are in the presence of a strong, rapidly changing magnetic field!. The chandelier is not plugged in, so presumably the filaments in the light bulb are not part of any closed circuit.  Yet there appears to be a current flowing through them all the time.  How is this possible?  (Hint: think AC!)

Helmholtz coils are a method developed to provide a uniform magnetic field in a small region. They are constructed by placing two identical wire loops parallel to each other, separated by a distance equal to their radii, as shown in the Figure. Assume that the two loops are also connected in parallel to a power supply, so that they produce the same field. (a) Find the length of a 28-gauge copper wire that will produce a 75 Ω coil. m...
