You asked: Where do the magnetic field lines begin and end?

Contents

Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

Do magnetic field lines ever start or end anywhere?

Magnetic field lines don’t start or stop anywhere, they always make closed loops and will continue inside a magnetic material (though sometimes they are not drawn this way).

Where is the magnetic field strongest?

The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.

Where do magnetic field lines originate?

From the properties of bar magnets, we know that the magnetic field lines responsible for the field originate at the north and terminate at the south pole, and are thus closed loops.

Why magnetic field lines are from north to south?

When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.

What does the closeness of magnetic field lines indicate?

Answer. The degree of closeness of field line represents the INTENSITY OF MAGNETIC FIELD. If the magnetic field lines are closer, the intensity of magnetic is strong and vise-versa. This intensity of magnetic field represents the strength of the magnet.

Do the field lines begin at the pole face group of answer choices?

North Question 2 0.5 / 0.5 pts Do the field lines really start at the pole face? Yes Correct! … In the figures below, the earth is shown with the northern hemisphere on top, its core magnet is illustrated by the overlaid bar magnet, and a compass is illustrated as a diamond with a black tip at its magnetic north end.

What is the weakest part of a magnetic field?

The magnetic field is weakest along the surface in the middle of the side of the magnet. This is a close-up of the field at the North pole.

Where is the weakest part of a magnetic field?

The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

Can you block a magnetic field?

The short answer is no, there is no shield or substance that will effectively block magnetic fields as such. You can however redirect the magnetic field lines, which is what some people call magnetic shielding. … The magnetic field lines are closed loops and must be continuous between a north and a south pole.

How magnetic field is created?

Any current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created.

Can we see magnetic flux lines?

At each end of a magnet is a pole. These lines of flux (called a vector field) can not be seen by the naked eye, but they can be seen visually by using iron fillings sprinkled onto a sheet of paper or by using a small compass to trace them out.

Why can’t magnetic field lines cross?

Magnetic field lines can never cross, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

What exactly is a magnetic field?

The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other.

Does a compass always point north?

While a compass is a great tool for navigation, it doesn’t always point exactly north. This is because the Earth’s magnetic North Pole is not the same as “true north,” or the Earth’s geographic North Pole . … This difference between true north and the north heading on a compass is an angle called declination.

How can you tell how strong a magnetic field is?

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.
