The opposition to the formation (not 'flow') of magnetic flux is the ampere per weber (often spoken as 'ampere-turn per weber'). This is derived from dividing the magnetomotive force produced by a winding, expressed in amperes (often spoken as 'ampere-turns'), divided by the resulting magnetic flux. expressed in webers.

How demagnetize an electric motor?
A transformer winding only produces a magnetic field when current flows through it. Switch the current off, and the magnetic field disappears. You do not need to 'demagnetise' a transformer winding.
How does current flows when inductor n capacitor r in series?
The stronger the magnetic field on your inductor the greater amount of current you will have flowing through your series circuit.
How does an auxiliary transformer work?
Auxiliary transformer- current transformer The current transformer is working based on two theories. 1.Ampheres law. 2.Faradays law. Amp.law- whenever a current flows through the conductor it will produce magnetic flux around the conductor. based on above principle- current flows through the primary will induce a magnetic flux in the CT core. Faraday law- whenever a conductor cuts the magnetic flux or magnetic flux cuts the conductor will induce a emf across the conductor based on above principle- the magnetic flux in the core will cuts the windings. so emf is induced across the secondary terminals . whenever the secondary terminals connected with burden will make a closed path and current flows through the secondary to burden.
Is aluminium magnetic when a current is passed throu it?
When current flows through any conductor, there is a magnetic field around the conductor. It doesn't matter what substance comprises the conductor. I guess that means that aluminum wire can be an electromagnet, but not a permanent one.
What is the effect of field current on dc motor?
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
