Why do opposite magnetic poles attract?
A magnetic field is created when the atoms of a magnet line to the north or south pole of the magnet. When two opposite poles face each other, the fields, and the atoms inside the magnet, line up, and this causes the attraction between the poles.
What direction will a magnet line up in if it is free to move?
A freely moving magnet will align itself in a north-south direction, pointing towards the Earth's magnetic poles. This behavior is due to the magnet's natural attraction to the Earth's magnetic field lines.
Is it true or false that balanced forces can change an object's direction?
False. Balanced forces do not change an object's direction. Balanced forces only keep an object at rest or in a uniform motion in a straight line. If an object changes direction, unbalanced forces are acting on it.
What are the three basic characteristics of line?
The three basic characteristics of line are length, width, and direction. Length refers to the extent of the line, width refers to the thickness of the line, and direction refers to the path along which the line is drawn.
What is considered to be moving in the negative direction?
Motion in the negative direction typically refers to movement opposite the positive direction along a specific axis or line. For example, if we consider a number line, moving to the left would be considered moving in the negative direction.
What is produced if the poles of atoms line up in the same direction?
If the poles of atoms line up in the same direction, it creates a strong magnetic field. This alignment is the basis for ferromagnetism, where materials like iron and cobalt can become magnetic.
What is the produce if the poles of atoms line up in the same direction?

Is an absorption spectrum also called a bright line spectrum?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
Where is the international date line start?
The ends of the International Dateline are the north and south poles. But the line doesn't have any particular direction, so there's no such thing as its starting or ending point.
Why use a suspension insulator on 11kv electric power lines?
Suspension insulators are glass 'dish' insulators that are designed to take longitudinal strain -i.e. strain in the direction of the conductors. They are so-called, because they are suspended below the pole's crossarm. Suspension insulators, therefore, are used on terminal poles where the main strain on the crossarm is in the direction of the conductors, or on angle-poles where there is a sharp change in direction of the power line.
What is the imaginary line through Earth's poles called?
The imaginary line through Earth's poles is called the axis. It is an imaginary line that Earth rotates around.
What is the line between the two poles called?
The lines joining the two poles are longitudes.
How are magnetic poles created?
Magnetic poles are created by the alignment of electrons in a material. When the electrons in a material align in the same direction, they create a magnetic field with a north and south pole. Some materials have intrinsic magnetic properties due to the alignment of their electron spins, while others can be magnetized by exposing them to an external magnetic field.
Where do power line birds nest?
Atop the power line poles.
Is a cloths line a line a ray or line segment?
A clothesline is best described as a line segment because it has two endpoints where it is attached, typically to poles or walls. Unlike a ray, which extends infinitely in one direction from a single point, or a line, which extends infinitely in both directions, a clothesline has a defined length between its endpoints.
How are domains arranged in a magnetic object?
Without magnetic domains a magnet wouldn't have its magnetism. Magnetic domains are clusters of iron atoms that line up in the smae direction when magnetised. When unmagnitized the iron atoms scatter.
