Magnets can also attract each other, but only if they face in opposite directions. A magnet has two ends called
poles
; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other.
What are the parts of a bar magnet?
The bar magnet has
a north pole and a south pole at two ends
. Even if you break a bar magnet from the middle, both the pieces will still have a north pole and a south pole, no matter how many pieces you break it in. The magnetic force of it is the strongest at the pole.
Are both ends of a magnet the same?
A
magnet has two ends called poles
; one end is the north pole and the other is the south pole. 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.
Why are magnets stronger at the ends?
The magnetic field of a bar magnet is
strongest at either pole of the magnet
. … The field lines are closely packed at either pole of the magnet, widening as they get farther from the pole and connecting to the opposite pole of the magnet. The magnetic field lines emerge from the north pole and enter the south pole.
What are the ends of a magnet called?
The end that faces the north is called
the north-seeking pole, or north pole
, of the magnet. The other end is called the south pole. 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.
Which part of the bar magnet shows the strongest attractive property?
The end of the magnet pointing north is called the north-seeking pole (or, more simply, the north pole), and the other end is called the south (seeking) pole. The magnetic effect is strongest at
the poles of a magnet
. If a magnet is dipped into iron filings, many are attracted at the ends but very few at the centre.
What are applications of bar magnet?
Uses of Bar Magnet
Bar magnets are used as
stirrers in laboratory for magnetic experiments
. They also find applications in medical procedures. Electronic devices such as telephones, radios, and television sets use magnets.
Is electromagnet a permanent magnet?
Electromagnets: A permanent magnet is
a magnet that retains its magnetion
. A small permanent magnet can be used to hold notes onto the door of a refrigerator. … An electromagnet is a temporary magnet which magnetic field is produced by the flow of electric current in a coil wound round a soft iron core.
What would happen if you stroke an iron nail with a magnet?
After
stroking the iron nail repeatedly with
a magnet, the iron nail will become a magnet. We say that the iron nail has been magnetised. The greater the number of strokes you give the iron nail, the stronger its magnetism. … Iron filings are attracted to the magnetized iron nail.
What makes two 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).
What happens if you put a compass near a magnet?
The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet. … When you take the compass away from the bar magnet, it again points north. So, we can conclude that
the north end of a compass is attracted to the south end of a magnet
.
Are 2 magnets stronger than 1?
Yes, stacking multiple magnets together can make them stronger. Two or more magnets stacked together
will exhibit nearly the same strength as a single magnet
of the combined size.
Are magnets stronger at the ends?
The magnetic field generated by any magnet
is always strongest at either pole
. The magnetic force is equally as strong at both the north and south pole.
Which magnet is strongest?
Which shape of magnets is the strongest? The strongest shape of magnet is actually of
neodymium magnet in a steel pot
. This means that if you want the strongest possible magnet, you simply buy a neodymium magnet and put in inside a steel pot. This gives the strongest possible shape of magnet.
Which is the best procedure to make a permanent magnet?
Take two magnets put one North pole and one South pole on the middle of the iron
. Draw them towards its ends, repeating the process several times. Take a steel bar, hold it vertically, and strike the end several times with a hammer, and it will become a permanent magnet.
Is there a maximum attraction in middle of a magnet?
As we know, magnetic field lines align parallel to the length of a magnet. Therefore, at the center of a magnet, the magnetic attraction will be low. … The density of magnetic field lines
is maximum at the poles
, therefore, the attraction will be maximum at the poles.
