The Earth`s magnetic field
... Changing electric fields cause magnetic fields. An electromagnetic wave is created by the changing electric field of a spark, an antenna, or an oscillating molecule (greenhouse gas). The changing electric field then creates a changing magnetic field. ...

Scanning SQUID microscope
A Scanning SQUID Microscope is a sensitive near-field imaging system for the measurement of weak magnetic fields by moving a Superconducting Quantum Interference Device (SQUID) across an area. The microscope can map out buried current-carrying wires by measuring the magnetic fields produced by the currents, or can be used to image fields produced by magnetic materials. By mapping out the current in an integrated circuit or a package, short circuits can be localized and chip designs can be verified to see that current is flowing where expected.
