Best description of a magnetic field line?
A magnetic field line shows the direction a compass needle would point
Does a compass work best when close to magnet?
No. Being near a magnet (or magnetic field) completely puts off the compass as the compass is influenced by it and will not align with the Earth's natural magnetic field.
Why does the soft iron core increases the strength of magnetic field?
Iron core (usually soft iron core) is a highly ferromagnetic material. Ferromagnetic materials allows (and attracts) the magnetic field lines to pass through it. When such a material is used in the electromagnet, the magnetic field lines passing through it increases, thereby, the strength of the electromagnet increases. So my friend, I hope you are satisfied with the answer.
A conducting wire is placed inside a magnetic field. When the wire is rotated an electrical current runs through it. Which of these best explains why the wire needs to be rotated?
i
What is the most likely cause for the existence of the earths magnetic field?
The best hypothesis is a self-sustaining dynamo caused by the slow but inexorable motion of the electrically conductive core.

What is the best description of a magnetic field line?
magnetic field line is an imaginary line showing magnetic energy between a north and south pole .
What terms best describes the space surrounding a magnet in which the magnetic forces acts.?
Magnetic field
What best describes magnetic field lines?
Magnetic fields are produced because of moving electric charges, and visualizing the very complex mathematical relationships that fall under the magnetic field might become much easier if magnetic field lines were used. A higher density of field lines means a stronger magnetic field. Keep in mind that those lines do not actually exist; they are drawn only to visualize the strength of the magnetic field.
What is the theory that explains the source of Earth's magnetic field called?
The source of Earth's magnetic field is best explained by _____.domainsthe dynamo theoryCoulomb's lawelectrostatics
Does a compass work best when close to magnet?
No. Being near a magnet (or magnetic field) completely puts off the compass as the compass is influenced by it and will not align with the Earth's natural magnetic field.
Which of these the best description of a field observation?
research that includes interviews and informal conversations
What is the best description of a direct primary?
a process by which members of a political party choose the candidates who will run for election.
Where is the magnetic pole in 2007?
Fluctuations in the magnetic field cause the Magnetic North Pole to constantly move in an irregular path around its average position. The position of where the Magnetic North Pole is given each year is actually an AVERAGE position, as the Magnetic Pole can move around up to 80 Km or more if the magnetic field is disturbed. One of the best links to predict where the North Magnetic Pole MAY be is the Woods Hole Marine Magnetism Group link attached.

What is the best way to describe induction?
a) The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body. b) The production of an electric current in a conductor by a change of magnetic field.
