well as the name mention production of magnetic field due to rotation. if we consider three identical coils axis physically by120* each and 3 phase supply given then their is the production of aleternating magentic field in each coil
any device with an electric flux
Motor
These devices are called generators, alternators, magnetos, or dynamos. These devices produce electrical energy from mechanical energy. The opposite is a motor which produces mechanical energy from electrical energy.
ammeter
A compass.
A magnetometer is a device that is used to detect magnetic fields on the seafloor. It was invented by Sheldon Breiner.
You can use a device that detects magnetism. A compass needle may suffice.

That's how every electric generator works.

An electric Generator.
generator
Electro-magnetic induction . a rotating force-field, so to speak. sounds very sci-Fi but a basic electrical device.
Any device with an electrical current will create a magnetic field. A tube of wire coils with a current running through it is called a solenoid and it will produce a magnetic field through the inside of the tube, as well as around it... Sorry, not much for physics.
