If iron piece is place in its field, the direction of the magnetic lines of force change towards North and South as in the case of a magnet. North represents North Pole and South for South Pole.

But note since the lines of magnetic force are of equal character, these repel themselves from each other.
Which is why they are spread out! (Seldom commented on.)

Wiki User
∙ 8y agoDomains would be aligned to be in the direction of the external magnetic field and so an intense magnetism would be induced in the iron piece.

How does earths magnetic field change over time?
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.
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 do magnetic bands provide evidence that tectonic plates are moving apart at mid-oceanic ridges?
Through seafloor-spreading as iron rich minerals cool they become magnetized in the direction parallel to the existing magnetic field. As the magnetic fields change direction so will the magnetized minerals, allowing scientists to record each change in the seafloor as it spreads.
What happens when you change the angle of a swash plate?
Direction of helicopter changes slightly
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.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
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?
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 additional factor will be change if the direction of a current flow is change?
direction of 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 does the lenz law state?
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.
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.
How could you change the direction in which a compass needle points using a cell and a piece of wire?
The compass will react to magnetic fields, and magnetic fields are caused by currents. Therefore, holding a current-carrying wire close to the compass is enough to change the direction in which it points.The compass will react to magnetic fields, and magnetic fields are caused by currents.

In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current
Does current affect electromagnetism?
Does current affect electromagnetism? No. Does current affect magnetic fields? Yes. The laws (Maxwell's Equations) pertaining to electromagnetism is constant and will not change regardless of current applied. However, Maxwell's equations does dictate that a change in current will essentially result in a change in magnetic fields. Current flow will produce a magnetic field perpendicular to the current direction.
What happens when there is a change in the magnetic field in a closed loop of wire?
It produces a current.
