Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.
Who is considered the father of electromagnetism?
James Clerk Maxwell is often credited as the father of electromagnetism due to his formulation of Maxwell's equations.
What are Maxwell’s equations?
Maxwell's equations are a set of four equations that describe the behavior of electric and magnetic fields and their interactions with matter.
What is an electromagnetic field?
An electromagnetic field is a field produced by electrically charged objects and can affect the behavior of other charged objects in the vicinity.
What is the speed of light in a vacuum according to Maxwell's equations?
The speed of light in a vacuum is approximately 299,792,458 meters per second.
How do electric currents create magnetic fields?
Electric currents create magnetic fields according to Ampère's circuital law, which states that an electric current produces a circular magnetic field around the current.
What is electromagnetic induction?
Electromagnetic induction is the process of generating electric current with a changing magnetic field, discovered by Michael Faraday.
What is Faraday's Law of Induction?
Faraday's Law states that the induced electromotive force in a closed circuit is proportional to the rate of change of the magnetic flux through the circuit.
What is the Lorentz Force?
The Lorentz Force is the force experienced by a charged particle due to electromagnetic fields, calculated as F = q(E + v × B).
What is a solenoid?
A solenoid is a coil of wire that generates a magnetic field when an electric current passes through it.
How does a transformer work?
A transformer changes the voltage of an electric current by using two coils of wire, called the primary and secondary coils, through electromagnetic induction.
What is the principle of superposition in electromagnetism?
The principle of superposition states that the net electromagnetic field caused by multiple charges is the vector sum of the fields from each charge.
What is Lenz’s Law?
Lenz's Law states that the direction of the current induced by a changing magnetic field is such that it opposes the change that produced it.
What is a magnetic monopole?
A magnetic monopole is a hypothetical particle proposed in some theories, having only one magnetic pole, either a north or south, unlike regular magnets.
What is Gauss's law for magnetism?
Gauss's law for magnetism states that the net magnetic flux through any closed surface is zero, implying there are no magnetic monopoles.
