Electric field probe

A probe is an instrument that can send an electronic signal that can be captured by a corresponding guide to accurately locate it. Generally divided into low frequency probes, high frequency probes and wired bars.

A field is a physics field that exists around a charge that transfers the interaction between charge and charge. There is an electric field generated by it around the charge; at the same time, the electric field acts on other charges in the field. The field observed by the observer relative to the charge at rest is called the electrostatic field. If the charge moves relative to the observer, a magnetic field appears in addition to the electrostatic field. In addition to the charge that can cause an electric field, a changing magnetic field can also cause an electric field, the former being an electrostatic field and the latter being called a vortex electric field or an induced electric field. The changing magnetic field causes an electric field. Therefore, the interaction between the moving charge or current is transmitted through the electromagnetic field.
