Question

What three conditions are necessary to create an EMI as demonstrated by the EMI triangle?

Answer 1

The three conditions necessary for electromagnetic induction are a changing magnetic field, an opposing emf, and a closed loop conductor.

Step-by-step explanation:

The three conditions necessary to create an Electromagnetic Induction (EMI) are:

1. A changing magnetic field that induces an electromotive force (emf) and an electric field.
2. The direction of the emf opposes the change in the magnetic field, according to Faraday's law of induction.
3. The presence of a closed loop or conductor where the emf can circulate, such as a wire or coil.

These three conditions form the basis of the EMI triangle, which is used to demonstrate the principles of electromagnetic induction.
