text: Magnetic fields are created by moving electric charge.
text: A magnetic field is generated by moving charges—i.e., an electric current.
text: Magnetic fields are created by things that are magnetic (like iron magnets) or by moving charged particles.
text: The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
text: When electrons, which have a negative charge, move around in certain ways, a magnetic field can be created.
text: When the convective motions occur with the electrical currents around the Earth, the magnetic field is created.
text: As current begins to increase, a stronger and stronger magnetic field will be created, absorbing energy from the source.
text: Magnetic fields are created when electric current flows: the greater the current, the stronger the magnetic field.
text: Magnetic fields are created only when the electric current flows.
text: When the convective motions occur with the electrical currents around the Earth, the magnetic field is created.
text: Magnetic fields are created by moving electric charges.
text: When electric current flows through the wire, a magnetic field is generated.
text: A magnetic field is generated when electric charge carriers such as electrons move through space or within an electrical conductor.
text: A magnetic field is generated by what’s called a dynamo, which is caused by the fluid motion of a conducting material, such as liquid iron.
text: The magnetic field is generated by swirling liquid metal in Earth's outer core, and this "geodynamo" requires the release of heat from the planet to drive its churning.
text: To begin, the magnetic field is generated from convection (circulation) of the Earth's predominantly iron (Fe) liquid outer core (the Dynamo Theory).
