# N-M17 Electromagnetism Module

## INNOVATIVE SYSTEMS

With the Electromagnetism Module, "N-M17", designed by EDIBON, the operation of electromagnetic applications such as transformer, solenoid, relay, stepper motor operation or DC motors can be studied.

See general description

## General Description

Electromagnetism is the interaction between electric charges. It is described in terms of charges interacting between of electric and magnetic fields.

With the Electromagnetism Module, "N-M17", designed by EDIBON, the operation of electromagnetic applications such as transformer, solenoid, relay, stepper motor operation or DC motors can be studied.

In addition, faults can be simulated in most of the circuits under study. The student must investigate what is happening in the circuit and why it is not working properly. These faults simulations can be of several types from damage components to a hypothetical incorrect circuit assembly.
