magnetic field Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from A current in a magnetic field experiences a force given by the equation F = I l × B or F = IlB sin θ, where l is the length of the wire, Moving magnetic fields pull and push electrons Metals such as copper and aluminum have electrons that are loosely held Moving a magnet around a coil of wire,
