At the centre of a bar magnet magnetism is?
At the center of a bar magnet, the magnetic field lines converge and form a strong magnetic field. This region is referred to as the magnetic core of the magnet, where the magnetic strength is at its maximum. This is why the bar magnet's strongest magnetic force is typically concentrated in its center.
How a solenoid may be used to demagnatise a bar magnet?
To demagnetize a bar magnet using a solenoid, the magnet can be placed inside a solenoid and the current can be gradually decreased to zero. This process disrupts the alignment of magnetic domains within the magnet, leading to demagnetization. The alternating current can also be used for more effective demagnetization.
What are the forces between a charge and a bar magnet?
The forces between a charge and a bar magnet are due to the interaction of electric and magnetic fields. Charges create electric fields, while magnets create magnetic fields. When a charge interacts with a bar magnet, the electric and magnetic fields can exert forces on each other, leading to attraction or repulsion between the charge and the magnet.
How many neutral points are form due to a bar magnet?
A bar magnet has two neutral points located at its midpoint, equidistant from both poles. These points are where the magnetic field strength is zero.
Why does the needle of a compass point south when it's put on a bar magnet?
When a compass needle is placed near a bar magnet, it aligns itself with the magnetic field created by the magnet. The compass needle is a small magnet itself, with its north pole attracted to the south pole of the bar magnet and repelled by its north pole. If the compass needle points south, it indicates that the bar magnet's south pole is near the compass's north pole, demonstrating the fundamental property of magnetic attraction and repulsion. Thus, the orientation of the compass needle reflects the magnetic field direction of the bar magnet.
What happens to a magnet force when a bar magnet is cracked through the middle?
If a bar magnet is broken in half, each half is a magnet with its own north and south pole. The force used to break the magnet will also tend to partially demagnetize the magnet, although that might be a minor effect.
Why does a bar magnet placed in S-N direction turn towards N-S direction when torque acting on it is zero?
If the bar magnet turned then there was a torque acting upon it. Torque is defined as a turning force or moment.
What location could you place the south pole of a var magnet so that it would be pulled toward the magnet shown?
To attract the south pole of a bar magnet, you would need to place it near the north pole of another magnet or in close proximity to the bar magnet's north pole. Since opposite poles attract, positioning the south pole of the bar magnet toward the north pole of the magnet shown will result in a pull toward the magnet. This attraction occurs because magnetic fields interact in such a way that opposite poles draw closer together.
Is there a scale for magnet strength?
They are bar magnet ,horse shoe magnet ,lime stone magnet.
How can you show that a given bar is a magnet?
The following two methods are really the same idea:1). Test against a known magnet. Observe whether there is an attraction or repulsion between them.2). Hang the bar by a string from its mid-point. Observe whether it shows a tendency to align itself in a preferred direction.Another method:3). Observe whether the bar picks up paper clips. ---- If you have two bars and are told that one of them is a magnet but the other is not, and you are not allowed to use any other metal, string, etc. to determine which is which, see which one is attracted to the middle of the other bar. That one's the magnet.
Is bar magnet a natural magnet?
no
What happens to the bar magnet as it nears the U magnet the bar magnet will?
Move towards the U magnet so that the poles attach.
