Why does the changing magnetic flux in a conducting loop always induced a current that generates field opposing the change in flux?

Free electrons in the conducting carry a charge, and electrons are influenced by magnetic waves. Thus if a magnetic wave is generated by the changing field, electrons will feel the influence. Since the system is naturally stable it will resist changes, and thus it opposes the influence. The current flowing in the conductor will generate a field opposing the incoming field.

How can the leakage flux be minimized in a dc motor?
An opposing magnetic field around the motor coil.
Why the generator field rheostat kept at maximum position?
There is nothing to limit current until opposing magnetic fields build up at generator operating speed-windings will overheat and burn.
Electric and magnetic fields move in what direction of each other and the direction of the wave?
Electrical and magnetic fields have liquid properties and by this I mean they move in waves and are bound by the properties therein and the Laws of Nature that control liquid states. There are many types of liquid states continuing out into space. These are about densities and those densitiies fall away infinitely. In conclusion Electrical and Magnetic waves would most likely repel each other if their poles aren't opposing. Positive to positive or negative to negative. Phil staples
If you increase the number of turns in the coil and move a magnet at the same speed will the speed increase or decrease?
no the strength of the magnetic field does not decrease because of the number of coils increases.
What is the scientific principle that makes a simple electric motor run?
In a permanent magnet motor, electricity is used to create an opposing magnetic field to the one existing due to the magnet. This creates a force that causes the motor to spin. In a motor without a permanent magnet, electricity is used to create two opposing magnetic fields.
Does induction motor has rotor winding?
Yes, the induction motor has a rotor winding. It is usually one turn, shorted. This is how the magnetic fields generated in the stator induce a current in the rotor, which subsequently generates a torque from the opposing magnetic fields, stator to rotor.
What is along the earths magnetic lines?
opposing magnets i guess?
What is fringing effect in magnetic field?
FRINGING EFFECT:Fringing effect is the magnetic characteristic caused by the shape around directly opposing the magnetic surfaces.
What is field effect?
Fringing effect is the magnetic characteristic caused by the shape around directly opposing the magnetic surfaces.
How can you conduct debate?
By getting an opposing topic for the two groups and conducting it by the interest of everyone who is debating.
How can the leakage flux be minimized in a dc motor?
An opposing magnetic field around the motor coil.
What is fringing electric field?
Fringing effect is the magnetic characteristic caused by the shape around directly opposing the magnetic surfaces.
Is it possible for the opposing magnetic field to be strong enough to completely stop an object from falling?
No because the magnetic field induced attracts the falling magnet, creating a force which slows down the magnet. If the magnetic field increased to a certain point where the force acting on the magnet was enough to stop the magnet from falling, gravity would act on the bob, causing the magnet to speed up again until it reaches a happy medium speed (or even a terminal speed if you will). When this happens, a changing magnetic field occurs and an induced current is formed again. This cycle repeats.
What is the hammer and anvil concept in conducting war by vo nguyen giap?
It is a strategy in which you attack the enemy with a line of infantry as you anvil and you use your calvary to hammer the anvil into the opposing force.
Who are the opposing sides in the Iraq war?
Criminals (terrorists). There is no flag, government or nation fighting the Iraqi government. There are simply criminals (terrorists) using various names and titles conducting acts of violence in that particular region.
State the important difference between a transformer and induction motor?
A transformer uses a varying magnetic field to induce a voltage in another winding, often changing the voltage to match the requirements of the load.A motor uses a varying magnetic field in induce a torque in the armature, making it turn, converting electrical energy into mechanical energy. In the case of an induction motor, the "windings" in the armature are built in as "single turn shorted secondary windings", rather than windings connected via slip rings or commutators, but the end result is the same - opposing and attracting magnetic fields cause the armature to rotate.
What are the two ways to increase the time of fall of a magnet through a tube?
If the tube is a conductor, the first way involving magnetism that will slow the magnet down is competely natural. When the magnet passes through a conductor, the changing magnetic field will induce a current in the conducting tube opposing the velocity of the magnet. This will cause the magnet to slow down through the length of the tube. The classic demonstration of this involves a copper tube and a small, round magnet. The second way involving magnetism is to wrap the tube in a coil of wire, creating a solenoid. After you have wrapped the tube, if you put a current that is counter-clockwise through the solenoid, the magnet will slow down because the solenoid creates a magnetic field that is directed upward. With this method, you could change the direction of the current and the magnet will fall faster instead.
