What happens to the field lines when two magnets are aligned with opposite poles?

This is shown in Figure 20.11, which shows the magnetic field lines created by the two closely separated north poles of a bar magnet. When opposite poles of two magnets are brought together, the magnetic field lines join together and become denser between the poles.

What happens when the positive poles of two magnets are placed near each other?

When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract.

How are magnetic field lines different from electrostatic field lines?

Answer: The electric field line induces on a positive charge and extinguishes on a negative charge, whereas the magnetic field line generates from a north pole and terminate to the south pole of the magnet. The electric field lines do not form a loop whereas the magnetic field lines form a closed loop.

Do magnetic field lines always form closed loops?

Are magnetic field lines closed loops? – Quora. Yes they form close loops because they can exist inside a magnet at any angle. They always forms close that means they start from North pole to South pole externally and South pole to North pole internally like this they form a close loop….

What is a magnetic field draw a diagram to show the magnetic field lines around a bar magnet?

(i) Two magnetic field lines never interest each other. (ii) Outside the magnet, the magnetic field lines are directed from North pole of the magnet towards the South pole. (iii) The magnetic field lines at any one point give the direction of magnetic field at that point.

Why do opposite ends of a magnet attract?

When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).

Whats the scientific reason of attraction between opposite pole of a magnet and repulsion of same pole and why its not possible to separate the two pole?

The same poles of a magnet do attract each other, while the opposite poles repulse each other. However, both the poles remain indivisible in a magnet. It is impossible to separate north pole to south pole or vice versa.

How will the same poles north to south and south react when put near each other?

A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away. We say the magnets repel each other.

How are magnetic field lines and electric field lines similar?

Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract.

What happens when two magnets are near each other?

When two magnets are brought close together, the magnetic field lines are perturbed, just as happens for electric field lines when two electric charges are brought together. Bringing two north poles together—or two south poles—will cause a repulsion, and the magnetic field lines will bend away from each other.

How do you map the magnetic field around a bar magnet?

(a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet. (Recall that the Earth’s north magnetic pole is really a south pole in terms of definitions of poles on a bar magnet.)

What are the magnetic poles of a magnet?

Magnetic poles are opposite ends of a magnet where the magnetic field is strongest. Let’s see what happens when two magnets are placed under the paper. When the two magnets approach each other, the lines made by the iron filings change shape. The two magnetic forces are interacting!

Where are the magnetic field lines most concentrated?

the field lines come out of N (north pole) and go into S (south pole) the field lines are more concentrated at the poles The magnetic field is strongest at the poles, where the field lines are most concentrated.
