Yes, hearing aids can emit low levels of electromagnetic fields (EMF), primarily due to the electronic components and wireless technologies they use, such as Bluetooth or telecoil systems. However, the EMF levels produced by hearing aids are generally considered to be very low and within safety limits established by regulatory agencies. Most users do not experience any adverse effects from these emissions. Overall, the benefits of improved hearing typically outweigh any concerns about EMF exposure.

Yes, power lines emit electromagnetic fields or frequencies due to the flow of electricity through them. These electromagnetic fields can vary in strength depending on factors such as the voltage and current flowing through the power lines.
Electromagnetic waves emit energy through oscillating electric and magnetic fields that propagate through space. This energy transfer occurs as the waves interact with matter, inducing changes in the atoms and molecules that absorb the energy. The absorption of electromagnetic energy can lead to heating, chemical reactions, or the generation of electrical currents.
Human bodies emit various types of electromagnetic radiation, primarily in the form of infrared radiation (heat) and extremely low-frequency electromagnetic fields produced by biological processes like nerve impulses and muscle contractions. These emissions are typically very low in intensity and are a natural part of the body's functioning.
In principle, electromagnetic energy can be measured. However, I am not quite sure what you mean by "the electromagnetic energy of a person". A person does not emit significant amounts of electromagnetic energy, except for infrared energy emitted by any object due to its temperature. If you mean that, yes, it can be measured as well.
Yes, guitar amplifiers emit electromagnetic radiation as a byproduct of converting electrical signals into sound waves. This radiation is generally considered low-level and not harmful to human health.
Modern televisions emit very low levels of radiation that are considered safe for everyday use. The amount of radiation emitted by a television is typically in the form of low-frequency electromagnetic fields, which are not harmful to human health when the TV is used as intended.
Hot objects emit infrared electromagnetic waves.
Humans emit visible light in the form of infrared radiation, which is a type of electromagnetic radiation.
Classical they will emit electromagnetic waves (light and radio waves). Quantum effects might limit this since if the electrons are in the ground state (or all lower states are occupied) they can not emit any photons (quanta of electromagnetic waves).
Humans emit infrared light, which is a type of electromagnetic radiation that is not visible to the human eye.
Electromagnetic energy is produced by the vibrations of electrically charged particles. This energy is composed of electric and magnetic fields that travel through space as waves. Examples include light, radio waves, and microwaves.
