Yes to all.
-- Electrical current in a toaster produces thermal energy, often known as "heat".
-- In a light bulb produces light.
-- In the wires dangling from eaqr-buds produces sound.
-- In a solenoid coil or motor stator produces magnetic forces.
To produce a rotating magnetic field, you need a three-phase electrical system with currents flowing through three separate windings spaced at 120 degrees apart. The currents must be of equal magnitude and have a phase difference of 120 degrees. This configuration creates a magnetic field that rotates due to the combined effect of the three phase currents.
Eddy currents in a magnetic drum can be produced by rotating the drum in close proximity to a magnetic field. The changing magnetic field induces currents in the metal drum, which in turn creates its own magnetic field that interacts with the original field, causing eddy currents to flow within the drum.
Electromagnetic energy is a form of energy that can produce heat, light, magnetism, and electrical charges. It consists of electric and magnetic fields that oscillate together. When these fields interact with matter, they can generate various effects such as heating, light emission, magnetization, and electric currents.
The three elements that produce a magnetic field are electric currents, magnetic materials, and changing electric fields. These elements interact to generate magnetic fields and are fundamental to understanding electromagnetism.
Any material that can conduct electricity can produce a magnetic field. The brain uses tinny amounts of electricity to move messages around itself so the brain produces a very small magnetic field that Medical Doctors using very sensitive equipment may be able to detect
Yes.Yes.Yes.Yes.
Motion of a coil within a magnetic field will induce a current in the coil if it can complete a circuit.
yes
All electrical circuits produce a magnetic field around the wires when a current is travelling. If we want to generate a large field, we can coil the wire. Such a coil is called a solenoid.

No. Earth's magnetic field is produced by currents in the liquid outer core.
Alternators convert rotating mechanical energy into electrical energy. Alternators produce electrical energy by induction of the coil wires by the spinning electromagnet rotor. The back voltage and eddy currents produce a magnetic field that opposes the rotation of the rotor, conserving total energy.

The changing magnetic field induces currents in the metal drum, which in turn creates its own magnetic field that interacts with the original field, causing eddy currents to flow within the drum.
No. Any current produces a magnetic field. Look at Maxwell's equations.
A motor is not needed in a circuit, a motor is an electrical load for the current to drive, but the circuit can perform with other types of load - such as a lamp, a transformer, a heating coil, or any electronic load. if you mean 'why does an electric motor need a circuit?' this is because the motor is an electrical device which has coils of wire to produce a magnetic field, without the circuit it cannot function.
