A straight 2.9 m wire carries a typical household current of 1.5 A (in one direction) at a location where the earth's magnetic field is 0.55 gauss from south to north. a. Find the direction of the force that our planet's magnetic field exerts on this wire if it is oriented so that the current in it is running from west to east. b. Find the magnitude of the force that our planet's magnetic field exerts on this cord if is oriented so that the current in it is running from west to east. c. Find the direction of the force that our planet's magnetic field exerts on this cord if is oriented so that the current in it is running vertically upward. d. Find the magnitude of the force that our planet's magnetic field exerts on this cord if is oriented so that the current in it is running vertically upward. e. Find the direction of the force that our planet's magnetic field exerts on this cord if is oriented so that the current in it is running from north to south. f. Find the magnitude of the force that our planet's magnetic field exerts on this cord if is oriented so that the current in it is running from north to south. g. Is the magnetic force ever large enough to cause significant effects under normal household conditions?
