electromagnet Physics & Theory
81:What is Ampère’s Law?
A law relating magnetic field circulation to the electric current producing it: ∮B·dl = μ₀I_enc.
82: What is Faraday’s Law?
Faraday’s Law states that a changing magnetic field induces an electromotive force (EMF) in a conductor.
83: What is the right-hand rule?
A method to determine the direction of the magnetic field around a current-carrying conductor.
84: What is magnetic saturation?
The point where increasing H no longer increases B in a material.
85: What is the Curie temperature?
The temperature at which a material loses its ferromagnetic properties..
Electromagnet Magnetic Circuits
86: What is a magnetic circuit?
A closed path followed by magnetic flux, analogous to an electrical circuit.
87: What is leakage flux?
Magnetic flux that does not follow the intended path, reducing efficiency.
88: What is fringing effect?
The spreading of magnetic flux at the edges of a pole face.
89: What is a shunt?
A magnetic bypass to control flux distribution in a core.
90: What is a keeper?
A ferromagnetic bar placed across poles to reduce demagnetization.
