What can orient itself in a magnetic field?

Normally, compasses respond to Earth’s magnetic field, orienting themselves parallel to magnetic field lines. If we create a magnetic field that is stronger than Earth’s field—for example, by using electric currents—a compass needle will orient itself parallel to the new field.

Why is there a magnetic field pattern around the magnetic material?

Magnets create magnetic fields. These magnetic fields cannot be seen. They fill the space around a magnet where the magnetic forces work, and where they can attract or repel magnetic materials.

How do magnets align in a magnetic field?

A small magnetic object placed inside the magnetic field will align itself with the magnetic field lines such that the magnetic north pole of the object points along the field line towards the magnetic south pole of the magnet. A piece of iron can be picked up with a magnet, even if it is originally non-magnetic.

What is the direction of magnetic field lines around a bar magnet?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (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.

What is the name of the region around a magnet where magnetic force acts?

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.

Which of the following points lies in the region of highest magnetic field strength?

Hence magnetic force of lines are more crowded at the poles compared to the centre of magnet and hence strength of magnetic field at north and south pole magnet is more compared to centre of magnet. And therefore magnetic force is maximum at both the poles of the magnet compared to the centre of magnet.

Why direction of magnetic field lines is from north to south?

So the direction of field lines is determined by the direction of force. So in case of magnet consider a bar magnet having two poles , a north and a south . Opposite poles attract. So north poles seeks south pole and south pole seeks north pole .

Why are magnetic field lines curved?

Magnetic field lines are closed curves as they propagate from the North pole outside the magnet’s body to the magnet’s body and from the south pole to the north pole inside the magnet’s body. Hence, the magnetic field lines are closed.

Why do magnets align themselves?

Q7) Why does a freely suspended magnet always rest in north-south direction? Solution: As unlike poles attract and like poles repel, a magnet aligns itself in N-S direction.

Why do magnetic field lines come from the north pole?

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. The geographic north and south poles indicate the points where the earth’s rotation axis intercepts earth’s surface.

Why magnetic field lines are from north to south?

Magnetic field lines are always closed loops. They form as a point and expand outwards. When they vanish, they shrink to a point and then vanish. So field lines emerge from the north pole, travel around to the south pole and then complete the loop by travelling from south to north inside the bar magnet.
