# What Creates A Magnetic Field Quizlet?

## How do you detect a magnetic field?

A simple compass can detect a magnetic field and demonstrate its direction.

Iron filings can be used to show the shape of a magnetic field.

At the sophisticated level, a gaussmeter can detect a field and indicate its strength, as measured in gauss units..

## What does a magnetic field look like quizlet?

What does a Magnetic field look like? Shown by lines around a magnet . The lines always extend from one pole to the other, starting at north pole and end at the south pole.

## What does a magnetic field look like?

A compass works the way it does because Earth has a magnetic field that looks a lot like the one in a magnet. … Earth’s magnetic field gets stretched out into a comet-like shape with a tail of magnetism that stretches millions of miles behind the earth, opposite from the sun.

## What does a magnetic field affect?

Magnetic fields are areas where an object exhibits a magnetic influence. The fields affect neighboring objects along things called magnetic field lines. A magnetic object can attract or push away another magnetic object. You also need to remember that magnetic forces are NOT related to gravity.

## Is the rule for the interaction between magnetic?

How is the rule for the interaction between magnetic poles similar to the rule for the interaction between electrically charged particles? Like poles repel, unlike poles attract, and the force is proportional to the inverse square of the distance between two poles. … All magnets have both south and north poles.

## Which direction is relative to magnetic field?

What relative direction between a magnetic field and a current-carrying wire results in the greatest force? The wire should be perpendicular to the field. How does a galvanometer detect electric current?

## What is a magnetic field flip?

A geomagnetic reversal is a change in a planet’s magnetic field such that the positions of magnetic north and magnetic south are interchanged (not to be confused with geographic north and geographic south).

## Why can’t magnetic field lines cross?

TWO MAGNETIC FIELD LINES CANNOT INTERSECT EACH OTHER BECAUSE IF THEY INTERSECT THEN THERE SHOULD BE TWO TANGENTS AT A POINT , WHICH REPRESENTS TWO DIRECTION OF MAGNETIC FIELD AT A POINT , AND IT IS NOT POSSIBLE.

## What happens when magnetic fields overlap?

When magnets are close together, with their fields overlapping, the fields combine to produce a resultant field which acts in one direction at any given point. The point X is called a neutral point. The forces due to both magnets cancel each other, i.e. there is no net force, at X.

## Why do magnetic fields have lines?

By convention, the lines trace the force from the north to south pole of a magnet. The distance between the lines indicates relative strength of the magnetic field. The closer the lines are, the stronger the magnetic field is.

## Why do magnetic lines of force move from north to south?

Magnetic Field Lines. Unlike Poles Attract Each Other. … If on the other hand, the like poles, i.e. the north and the north pole (or the south and the south pole) are placed close to each other, the magnets do not link and the magnets repel each other. This is why the needle in a compass always points north/south.

## What produces a magnetic field quizlet?

What produces a magnetic field? Electric charges in motion. Charged particles in motion have both an electric field and magnetic field associated with them.

## What is a magnetic field quizlet?

Terms in this set (14) A magnetic field is a region where. magnetic materials and wires carrying currents experience a force acting on them. In field diagrams the field lines always point from the. north pole of the magnet to the south pole.

## What creates a magnetic field?

A magnetic field is a vector field that describes the magnetic influence on an electric charge of other moving charges or magnetized materials. … Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time.
