Research the current that your household electronics have. Are design choices effected by the magnetic fields generated by the current in these electronics? To try in the lab (Simulation) Calculate the magnetic field from a loop of current at all positions in space (not only on the axis of symmetry). Propose an experiment to characterize the magnetic field produced by Helmholtz coils. Propose an experiment to build and test a coil gun.
