The Electric field Generally points away from positive charge and towards negative charges. Generally points away from negative charges and toward positive charges Generally points along lines of constant potential Circles around charge carrying conductors. The earth has a substantial magnetic field because its iron core is magnetized because of electrical currents in its core because of thunderstorms. just to confuse us.

Solution

3. The electric field is generally points away from the positive charge to negative charge only. While defining the electric field E = F/Q where Q is the positive test charge of unit magnitude. If the source charge is positive then E will be away.

4 The magnetic field of earth arises due to molten lava with metal ions constitue the current which flows in the core
