WebInductive Sensors: Inductive proximity sensors detect the presence of metallic objects without physical contact by using electromagnetic induction. When a metal object approaches the sensor’s coil, it disturbs the magnetic field and alters the coil’s inductance, triggering the sensor. WebEpisode 414-4: Investigating electromagnetic induction (Word, 219 KB) A simple experiment (or demonstration) can be done by passing a permanent magnet through a coil of wire that is connected to a data logger. This shows clearly that as the magnet moves into the coil an EMF is generated for a short time.
