Consider a single coil carrying a current I.
a. What are the electric and magnetic fields at the center of the coil?
b. Now suppose the coil is moving at a speed v perpendicular to its axis. What are the electric and magnetic fields at the center of the coil?
c. What is the physical origin of the electric field you just found? Where are the charges?

A 20 cm3 aliquot of a 0.0577 mol dm-3
vanadium(V) solution wasreduced by iodide ions to
an unknown oxidation state (x). The liberated
iodine (I2) was titrated with 10.2 cm3 of a
0.0986 mol dm-3 Na2S2O3
solution.
Calculate the experimental value for the unknown oxidation state x
(to two decimal places).

A particle of mass m is constrained to a circle of radius r0: that is, the potential for the particle is 0 when the
particle is anywhere on that circle and infinite everywhere else,
?(?) = 0 (r=r0)
V(r) = ∞ (? ≠ ?0)
