Earths magnetic poles reverse approximately every years?
The process of the reversal of the Earth's magnetic poles is called a magnetic flip. This occurs every 4 or 5 times per million years.
What is true of any ferromagnetic materials?
It has an abnormally high magnetic permeability, it has a definite saturation point, and it has appreciable residual magnetism and hysteresis. That's why it remains magnetic even after the forcing magnetic field goes away.
Is a magnetic domain in everything?
No, magnetic domains are a phenomenon that only occurs in ferromagnetic materials.
A process in which magnetically susceptible material is extracted from a mixture using a magnetic force?
The process is known as Magnetic separation.
What is the process by which Earth's magnetic poles change places?
Magnetic reversal
What is saturation in magnetic materials?
saturation occurs when a magnetic material is as magnetized as it can get.
Do the formation of stalactites and stalagmites occurs in the zone of saturation?
yes,it occurs

When the forward saturation in Bipolar junction transistor occurs?
Forward saturation in a BJT occurs when the ratio of collecter-emitter current and base-emitter current reaches hFe or dc beta. A that point, the BJT is no longer operating in linear mode.
Why is air gap is necessary in particle magnetic circuits?
Mainly air gap is necessary in magnetic circuit for two necessary reasons: 1. to prevent saturation 2. to allow an object to move in the magnetic field

What is the process by which water from precipitation and runoff is added to the zone of saturation?
recharge
What is the limit for magnetic field developed for a DC machine?
The magnetic field used in machines is quantified in terms of its flux density (symbol: B), expressed in teslas. The flux density is established by the magnetic field strength (H), expressed in amperes per metre, set up in the field windings.As the magnetic field strength increases, the flux density increases until it reaches saturation. This is the point when the magnetic domains within the magnetic circuit are all aligned. At this point, any further increase in magnetic field strength will fail to increase the flux density.So saturation of the magnetic circuit limits the flux density of the field.
What transformation occurs in a galvanometer?
It transforms into a magnetic field.
A process in which magnetically susceptible material is extracted from a mixture using a magnetic force?
