What is magnetism and is it necessary to have magnetism in order to travel with a spacecraft in space?

The magnetic fields of the Sun and the Earth are caused by moving electrically conductive material inside the Sun and Earth (plasma for the Sun and molten iron for the Earth). You don’t need magnetism to travel in space.
