What is the relationship between electricity and magnetisum?
The magnetic field will be perpendicular to the electric field and vice versa.More DetailAn electric field is the area which surrounds an electric charge within which it is capable of exerting a perceptible force on another electric charge. A magnetic field is the area of force surrounding a magnetic pole, or a current flowing through a conductor, in which there is a magnetic flux. A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid.The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles.The electrostatic force between charged particles is an example of this relationship.
What is made by passing an electric current through coils of wire?
An electro magnet is created when a current is passed through a coil of wire. This effect is the main operation of how an electrical solenoid operates.
Why DC current is not used in transformers?
A transformer couples energy from the input winding to the output winding by means of a changing magnetic field. AC current is a changing electric field, which produces changing magnetic fields when put to a wire and so is ideal for a transformer. This fact is why virtually all power distibution is AC. If DC were put to a transformer, once the winding magnetized in a fraction if a second, the current drawn would be so much it would blow the circuit. In other words, you can not use DC on a transformer because the transformer would be blown up by it.Another AnswerWhen any current passes through any conductor, invisible Electro-Magnetic fields are produced in the immediate space around the conductor; the strength and distance of these fields are proportional to the amount of current that passed through the conductor. The electric field is in the plane of the conductor while the magnetic field is perpendicular to the conductor. If the current is DC, the fields grow to their maximum and stay there. If the DC source is removed, the fields collapse. If there is enough current passing through the conductor, the fields will expand, break away from the conductor, and continue to propagate through space at the speed of light. This is the principal of a radio and TV station antenna. This propagation is also a direct loss of source energy.Induction is described as the relative motion of a conductor through a magnetic field. This can either be the magnetic field in motion with a fixed conductor, or a fixed magnetic field with the conductor in motion. Either of these conditions will induce an electric current in the conductor.Transformers work under the principal of induction. There is a primary coil and a secondary coil in transformers. The core of the transformer can be air, iron powder, or solid iron; among other material configurations. The ratio of the windings from the primary to the secondary determines if the voltage will be stepped up or down in the secondary. If there are twice as many windings in the secondary as are in the primary, the output of the secondary will be twice the voltage and half the current of the primary. If there are twice as many windings in the primary as are in the secondary, the output of the secondary will be half the voltage and twice the current of the primary. This rule does not take into consideration any loss in the field generation due to: counter EMF, impedance, propagation, etc.Since the transformer relies on the principal of induction, there has to be a relative motion between the magnetic field and the coil. If you apply a DC source to the primary of the transformer while watching the output of the secondary, what you'll see is a spike on the secondary where the magnetic field in the primary expanded, cutting through the secondary coil, but did not contract. This does not constitute the fundamental requirements of sustained induction. The above contributor is correct when saying the primary would draw as much current as the DC source could provide, usually ending in some catastrophic failure. The reason the DC current could run away is there is minimal resistance in the primary coil wire to DC current.There is, in fact, a form of resistance to an AC source applied to a coil. This is known as impedance and is caused by some of the factors mentioned above, mainly "Counter EMF". Counter EMF is a phenomenon produced because one loop of the winding is lying next to the next loop in the winding; when current is sent through the coil. When the magnetic field in the first loop starts to expand, it does so in a particular direction. The "Right Hand Rule of Thumb" can be applied to this scenario to determine which direction the magnetic field is traveling around the wire. Imagine using your right hand to wrap your fingers around a wire with your thumb pointing in the direction of current flow. Your fingers point in the direction of the magnetic field. When this magnetic field expands through the next loop in the coil, it induces a small amount of current in the opposite direction of the source current, which acts as a dynamic resistance to the main current source. This impedance is why current lags voltage by 90° in an inductive circuit.This subject is both broad and deep.
How micro ohm meter work in detail?
A current is passed through a resistor and the voltage drop is measured on the other side. It follows Ohm's law by a given current and voltage you can measure the resistance of a resistor by V=IR.
What Things do Conductors Have in Common?
If you are talking about electricity then all conductors have either de-localised electrons in their structure which means when a current is passed through they will move and carry the current with them. Ions can also carry charges but they have to be in solution or in liquid form.
What shape is the magnetic field produced when current is passed through wire?
CIRCULAR
Will magnetic field is produced when current is passed through a thick conducting sheet?
Yes,,,a current carrying conductor wil produce magnetic field around it.
What is magnetization current?
There is no magnetic current because there are no magnetic charges.
How is mechanical force produced on a wire when it is passed through a wire in a magnetic field?
The movement through a magnetic field will induce a voltage; if there is a closed circuit, that will produce a current. The current, in turn, will have a magnetic field, which will interact with the external magnetic field. The direction of the interaction will be such that energy is conserved, i.e., it will tend to slow the wire down.
When an electric current is passed through a coil what does this create?
A magnetic field.
What is formed around a conductor when a current is passed through it?
A magnetic field.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
What does a conductor do in a magnetic field when current is suddenly passed through it?
the conductor has to be moved.
How does an electric coil works?
when u give supply to a coil then a current will be passed through it .naturally a magnetic field is produced around the c.c.c(current carrying conductor). when u make more turns in the same direction the whole magnetic field will be stronger than that of a wire has. andby lenz's law there will be an opposition to the changing current in a coil due to the change in magnetic field produced
When electric current is passed through water which gas is produced on cathode?
When an electric current is passed through water oxygen gas is produced on cathode because oxygen is positive and cathode is negative . So, oxygen is produced.
Why steel becomes a permanent magnet after electric current is passed through it?
Electric current is magnetic so when electric current pass through steel , steel will have the electric power and may be magnetic for awhile
Is copper wire is magnetic?
it produces a magnetic field. i think that if current is passed through the wire it can attract pieces of iron
