How does the electromagnetic force work? Is magnetism chemistry or physics? Discuss. How is a magnetic field produced in an electromagnet? How do electrons create a magnetic field? How do you measure magnetism? How does moving a magnetic field create an electric field?
Step-by-Step Solution:1. Understanding Electromagnetic Wave Production: - Electromagnetic (EM) waves are produced by accelerating charged particles. When a charged particle accelerates, it disturbs the surro
A solenoid is another form of electromagnet. It's an electromagnetic tube generally used to move a piece of metal linearly. Find a drinking straw or an old pen (remove the ink tube). Also find a small nail (or a straightened paper clip) that will slide inside the tube easily. Wrap 100...
Static electricity or ESDis an electrical charge at rest. This is created by an imbalance of electrons that stay on a specific surface, or in the environmental air. The imbalance of electrons is caused by absence or surplus of electrons. This creates an electrical field that is capable of in...

How are electromagnetic waves produced by accelerating charges? What machine uses electromagnetic force? How can a magnetic field produce an electric current? Why is electromagnetic force stronger than gravity? How does electricity cause magnetism?
Electromagnets are magnets whose magnetic field is produced by an electric current. It displays a magnetic attraction to other metallic objects when an electric current is passed through them. We can also control and switch on and off the power of its magnetic attraction. ...
Electric energy is produced in the generators. By using the principle of electromagnetic induction, the magnetic field around conducting wires is changed and this creates the potential difference. This results in the formation of electric energy. Show More ...
A rotor winding carrying an induced current is subjected to an electromagnetic force in a rotating magnetic field, which produces an electromagnetic torque that drives the rotor to rotate. The direction of rotation of the rotor is the same as that of the rotating magnetic field. ...
Eventually, equilibrium is reached, and we have an electric field separating the two sides. This electric field acts as a diode, allowing (and even pushing) electrons to flow from the P side to the N side, but not the other way around. It's like a hill — electrons can easily go ...
