Do the wire act as inductance?
Yes, even a straight piece of wire has inductance. One metre (or yard) of household flex has about 800nH (0.8uH) of inductance. Winding wire into coils makes them more compact, and multiplies the inductance of the assembly through coupling between turns. Using straight pieces of wire, the inductance is proportional to the length, but in a coiled inductor with 100% coupling, the inductance is proportional to the turns (length) squared! In many applications, iron or ferrite cores are used to further increase the inductance.
The coefficient of coupling between two air core coils depends on?
Mutual induction only
What factors of an electromagnet affect the strength of the magnetic field?
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
What factors control the strength of an electromagnet?
The strength of an electromagnet is determined by the density of coils surrounding the magnet, and the rate of current passing through those coils.
What happens to an electromagnet when electricity runs through it?
When an electric pulse runs through an electromagnet, the current travels in the electromagnets coils, causing a magnetic field to be developed inside and outside of the coils. The amount of coils, tightness of the coils, and the space between the coils are all very important factors in the production of said EM field.
What is mutual conduction in magnets?
Mutual inductance is where the magnetic field generated by a coil of wire induces voltage in an adjacent coil of wire. A transformer is a device constructed of two or more coils in close proximity to each other, with the express purpose of creating a condition of mutual inductance between the coils.
What is meant by mutual inductance?
Mutual inductance is where two electrically separate coils of wire are either close to each other or share the same core. An alternating current flowing in one of the coils will 'induce' a current to flow in the other coil. For example by using coils wound with wire of the correct length and thickness, a transformer fed by mains electricity can by mutual inductance, produce a lower voltage to power your PC or radio.CommentMutual inductance occurs when a changing current (a.c. or d.c.) flowing in one coil induces a voltage (not a current!) into a second coil.
What are the Example each for self induced and mutually induced emf?
if an emf is induced in a coil due to the current flowing through itself is called SELF INDUCTANCE. on the other hand if an emf is induced on another coil due to the current flowing through the previous coil then it is called MUTUAL INDUCTANCE. suppose there are two coils A and B a current is flowing through A. now if the flux produced due to this current induce an emf on the same coil A, then it is SELF INDUCTANCE, and if it produce emf on B, then it is MUTUAL INDUCTANCE due to coil A.
What device employs mutual induction?
Mutual inductance OR induction refers to two independent coils which are electrically isolated but magnetically coupled through a path of low reluctance .This will cause most of the energy produced in the primary side to transfer to the secondary with minimal losses.That is why transformers which functioning on the principle of mutual induction has efficiency nearly 99%.
Does inductance increase the currents?
since both coils will have resistance, yes; but the load will be the primary amp draw
What is the Mechanism of the transformers?
Mutual induction between 2 or more coils.
What factors affect the comfort of a mattress?
Things that affect the comfort of a mattress are the actual construction - the springs or coils that are inside and also the materials and fabric used to manufacture the mattress.

What components can be include in integrated circuits?
Except coils (inductance) all other active and passive devices could be included in an ic
