What does it mean when the magnetic field lines are spread out? Magnetic field lines spread out from one pole,
curve around the magnet, and return to the other pole
. Arrows point from the north pole toward the south pole. Closely spaced field lines indicate strength, while lines spaced far apart indicate weakness.
What does more magnetic field lines closer together tell us?
the closer the lines,
the stronger the magnetic field
(so the magnetic field from a bar magnet is strongest closest to the poles) the lines have arrowheads to show the direction of the force exerted by a magnetic north pole.
What do magnetic field lines represent?
The magnetic field around a current-carrying wire can be increased by coiling the wire or increasing the current running through it. In a magnetic field, the field lines represent
the force the north side of a magnet might experience if it were in the field at that point
.
What do field lines tell you?
Electric field lines reveal
information about the direction (and the strength) of an electric field within a region of space
. If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location.
How magnetic field is created?
Conversely, a magnetic field is
produced by an electric charge in motion
. This is in accordance with Faraday’s Law of Induction, which is the basis for electromagnets, electric motors and generators. A charge moving in a straight line, as through a straight wire, generates a magnetic field that spirals around the wire.
Where the magnetic field is strongest?
So, the magnetic field is strongest
around the poles of the magnet
. Hence, the correct answer is option (A) Poles of the magnet. Note Magnets have two poles, a north pole, and a south pole.
How can you tell where the magnetic field is strongest?
The magnetic field is strongest
at the poles
, where the field lines are most concentrated. Field lines also show what happens to the magnetic fields of two magnets during attraction or repulsion.
What happens when two magnetic fields interact?
When opposite ends of two magnets interact,
their field lines connect the north pole of one with the south pole of another, and the two attract
. When the same ends of two magnets interact, they repel because the lines cannot cross and are compressed by each other.
How do you find field lines?
Start your search for the septic tank lines at the house. Trace the plumbing drain lines to the septic tank, which is usually installed 10 to 20 feet from the home’s exterior. At the tank’s end opposite the house, the drain line leads to the leach field. Check the
natural slope of the land
to locate the leach field.
What are the three rules for drawing electric field lines?
- 1) Electric field lines are always drawn from High potential to. …
- 2) Two electric field lines can never intersect each other.
- 3) The net electric field inside a Conductor is Zero.
- 4) Electric field line from a positive charge is drawn radially outwards and from a negative charge radially inwards.
Are electric field lines always straight lines?
In an uniform electric field,
the field lines are straight, parallel and uniformly spaced
. The electric field lines can never form closed loops, as line can never start and end on the same charge. … If the electric field in a given region of space is zero, electric field lines do not exist.
Can you see a magnetic field?
Magnetic fields are everywhere–
you just can’t see them*
. … Usually, that’s earth’s (relatively weak) magnetic field. But they also can be used to probe the field structure around stronger magnets, as they align to the sum total field at any given location. Compasses are easy to make.
Do magnetic fields exist?
However,
purely magnetic fields do exist
. Therefore, magnetic fields are more than just relativistic electric fields. The correct statement is that electric fields and magnetic fields are both fundamental, both are real, and both are part of one unified entity: the electromagnetic field.
What is an example of a magnetic field?
Examples of magnetic force is
a compass, a motor
, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters. All moving charges give rise to a magnetic field and the charges that move through its regions, experience a force.
Why magnet is strongest at its pole?
For a magnet, the flux lines repel each other so the field will be weaker at the sides. But
they are concentrated at the poles
, where they originate, so the field is stronger.
Where is the strongest magnetic field in a coil?
The strongest external magnetic fields are
near the poles
. A magnetic north pole will attract the south pole of another magnet, and repel a north pole.
