Definition of Diameter

In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.

Diameter is used to describe a physical dimension of an object. In the case of RVmagnetics, the diameter of a MicroWire sensor (meaning the length of an imaginable line that would pass through a MicroWire horizontally) is 3–70 µm, where:

• metallic alloy nucleus diameter: 1–50 µm
• glass coating diameter: 2–20 µm
