How do paired electrons affect the magnetic properties of a material?
Because of a property called spin, electrons act like tiny magnets. Most of the time paired electrons contain opposite spins, meaning the material has a weak magnetic field. The more paired electrons a material has, the weaker the magnetic field in the material. Unpaired electrons attract and repel other material. This determines which materials unpaired electrons match up with and attract to form a magnetic domain.
Why there is an induced current in a coil when the bar magnet is thurst into the coil?
This is called ELECTROMAGNETIC INDUCTION. The electrons have a magnetic field; the magnetic fields of electron and bar magnet interact. Both the bar magnet and the electrons are "pushed". The electrons are lighter; they move more easily. Moving electrons are called a current.
Why are some materials attracted to magnets and others not?
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.
Can storage media be damaged by magnetic and electric fields?
Yes; if the storage is on magnetic media then that can be altered by magnetic and electric fields.
Can an electric field be compressed?
Electric fields are similar to magnetic fields, and can be "compressed" by the imposition of other electric or magnetic fields.
What part of an atom is responsible for producing magnetic fields?
electrons
Do magnetic fields affect camera film?
No

What are all the sources of magnetic fields?
the poles (north and south) create the magnetic fields Magnetic fields are, in the end, the result of the movement of electrostatic charges. Any charged particle will create a magnetic field around its path of travel. (And, conversely, it can be affected by an external magnetic field.) It could be the separation of charges that creates a magnetic dipole, as in an atom. (Positive nucleus with the negative electron cloud about it.) It could be the movement of electrons in a conductor. (Electric current flow in a wire.) One of the four basic forces in the universe is the electromagnetic force. Not the magnetic force, but the electromagnetic force. If there's no moving charge, there's no magnetic field. The two phenomenon are intrinsically connected.
Do magnetic domains of iron naturally align with earth's axis?
Magnetic domains have the tendency to align with magnetic fields. The Earth's magnetic field is relatively weak, but I would expect SOME alignment.
Does the temperature of a magnet affect its magnetic fields lines?
yes
What does magnetic fields affect?
it affects the other planets and its rotation
How can a magnet become demagnetized?
A magnet can become demagnetized by exposure to high temperatures, strong magnetic fields, or physical impacts that disrupt the alignment of its magnetic domains. These factors can cause the magnetic domains to lose alignment, weakening or eliminating the magnet's magnetic field.
Does moving electricity cause a magnetic field?
Magnetic fields are only caused by moving electrons. In the case of a current flow, this is the common experience.For a permanent magnet, this effect is caused by the alignment of a number of spinning electrons into a magnetic domain. All their spins pointing the one direction.The magnetic fields and loops on the Sun are caused by currents flowing in the Sun's body. At many thousands of degrees, it is impossible for a magnetic material to exist. This is known as the Curie Temperature - another discovery by Marie Curie - and is the temperature above which a magnetic may be maintained in a material. In essence, the thermal motions of the molecules are too vigorous to permit the creation of aligned magnetic domains.
How torque is developed due to alignment of two fields?
Torque is developed by, among other things as well, the magnetic attraction or repulsion of two magnetic fields, contributing through rotational leverage to produce a net torque.
Do paired electrons create magnetic fields?
No - magnetism is created by moving electric charges.
What is the relationship between earths magnetic fields and the northern and southern lights?
because of electrons
