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.
Electromagnet Materials Science
91: What is grain-oriented steel?
Steel with aligned crystalline structure for lower core losses in transformers.
92: What is Metglas?
A commercial amorphous metal alloy with low core loss.
93: What is permalloy?
A nickel-iron alloy with high permeability, used in sensitive electromagnets.
94: What is mu-metal?
A nickel-iron alloy with high permeability, used for magnetic shielding.
95: What is ferrite core loss?
Energy dissipation in ferrite materials due to hysteresis and eddy currents.
electromagnet Miscellaneous
96: What is a gauss meter?
A device measuring magnetic flux density.
97: What is a Helmholtz coil?
A pair of coils producing a uniform magnetic field for calibration.
98: What is a magnetic circuit breaker?
A breaker using an electromagnet to trip during overcurrent conditions.
99: What is a magnetic encoder?
A: A sensor using magnets to detect position or speed.
100: What is magnetostriction?
The property of materials to change shape under a magnetic field, causing vibration/noise.
