Well you could either directly measure the magnetic field produced by the electromagnet. Something as simple as a compass shows the presence of a magnetic field. Or you could measure the electric current induced by the magnetic field.
Progress In Electromagnetics Research was created in 1989.
he discovered electromagnetics
It is possible to power a car using electromagnetics. The power from an electromagnetic field allows recharging or powering of any device including a car.
Thales of miletus (an ancient greek city) experimented with electromagnetics and in that way created what today we know as static electricity. He waved a rod over a cloth with thingees on it and created electromagnetics.
It is called radiation.

In the field of electromagnetics, the symbol 'h' represents the magnetic field intensity. It is significant because it helps describe the strength and direction of the magnetic field in a given space, which is crucial for understanding electromagnetic phenomena and designing devices like antennas and transformers.
No, electromagnetics are not associated with the paranormal. Electromagnetism is one of the four known fundamental interactions that dictate how matter behaves. The others are gravity and the strong and weak nuclear interactions. Electromagnetic anomalies may be caused by solar activity, local geology, weather, building architecture, and human technology.
