Why does the induced current opposes the original cause in lenz's law?
The induced current creates a magnetic field that opposes the original cause of it because it is trying to resist the change in magnetic field in the area and the only way to do that is to create an equal and opposite magnetic field which leads to the induced current.
How the laws of magnetism are in the generation of elecrcity?
The laws of electromagnetism state that a changing magnetic field induces an electric current in a conductor. This principle is utilized in power plants where magnets and coils of wire are used to generate electricity through electromagnetic induction. By rotating a magnet near a coil of wire, the change in magnetic field induces an electric current to flow in the wire, creating electricity.
How does earths magnetic field change over time?
The Earth's magnetic field is constantly changing and has been fluctuating in strength and direction over geological time scales. These changes are driven by complex processes in the Earth's outer core, such as convection and flow of molten iron. The field can weaken or reverse direction over thousands of years.
Three ways for increasing magnetic strength of solenoid?
refers to various ways of making a magnet from magnetic materials.they include: stroking method, electrical method, magnetism through hammaring among others*Induction *Stroking method : 2 types which are single touch method and double touch method *Electrical method ( By keeping the material to be magnetized in a solenoid and passing Direct current through it)The three methods to make magnet are:induction: the process of producing a electric or magnetic effects in a material with an electric charge or a magnet.stroking: is the process of rubbing in one direction.electricity: is a process to do with electric charge, particularly the use of electric energy.The three methods of making magnets are:1. Single touch method2. Double touch methodand by electrical method.
What is formed when you spin electrons in a magnet?
It doesn't work like that. You can't make an electron have spin, remove its spin, or change the amount of its spin.What happens in a permanent magnet is that more electrons have their spin axis in one direction than in the opposite direction. Since the spin is associated with a magnetic field, that results in magnetism that can be observed externally.
What happens to magnetic field of a wire when you change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The magnetic field direction around the wire reverses when the direction of the current in the wire is changed. This is due to the right-hand rule that states the direction of the magnetic field is perpendicular to the direction of current flow.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
What happens to the magnetic field of wire when you change the direction of a current of the wire?
In that case, the magnetic field will also be reverted.
What is the direction of the induced current in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
How do you change the direction of a magnetic field?
You can change the direction of a magnetic field by reversing the flow of electric current in a wire or by changing the orientation of a permanent magnet. Alternating the direction of current in a coil can also reverse the direction of the magnetic field it produces.
How can one determine the direction of induced current in a circuit?
The direction of induced current in a circuit can be determined using Lenz's Law, which states that the induced current will flow in a direction that opposes the change in magnetic field that caused it. This means that the direction of the induced current will be such that it creates a magnetic field that opposes the original change in magnetic field.
What happen to the magnetic field of a wire when change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
What additional factor will be change if the direction of a current flow is change?
direction of magnetic field
How can we use Lenz's Law to determine the direction of induced current in each case?
Lenz's Law states that the direction of the induced current in a circuit is such that it opposes the change in magnetic flux that caused it. By applying Lenz's Law, we can determine the direction of the induced current by considering the direction of the changing magnetic field and the direction of the induced current that would oppose that change.
What happens when the electric current is reversed on am electromagnet?
When the electric current is reversed on an electromagnet, the direction of the magnetic field is also reversed. This means that the north and south poles of the electromagnet switch places. This change in polarity can have various effects depending on the application, such as reversing the direction of motion in a motor or changing the direction of attraction or repulsion in a magnetic system.
What is the statment of lenz law?
The direction of an induced emf or current is such that the magnetic field created by the induced current opposes the change in magnetic flux that created the current.
