Motion.

The key ingredient for electromagnetic induction is A) Motion. Electromagnetic induction is the process of generating an electric current in a conductor by moving it through a magnetic field or varying the magnetic field around it. This motion is what creates the change in magnetic flux and induces an electromotive force (EMF) or voltage in the conductor. To understand why motion is the key ingredient, we need to comprehend the basic principles behind electromagnetic induction.

To get the answer, we can break down the concept of electromagnetic induction and identify its main requirements. Electromagnetic induction relies on a few key factors:

1. Magnetic Field: A magnetic field is necessary to induce an electric current. This can come from a permanent magnet or by creating a magnetic field using an electromagnet.

2. Conductor: A conductor, typically a wire or coil, is required to carry the induced current. Conductors allow the movement of electric charges.

3. Motion: The conductor must be in motion relative to the magnetic field, or the magnetic field should be varying. This is a crucial factor for inducing the electric current. If there is no motion or variation in the magnetic field, induction cannot occur.

By analyzing these factors, we can determine that motion is the key ingredient for electromagnetic induction. Without motion, there will be no change in the magnetic flux, and therefore, no induction of an electric current.
