What happens when you dip a bar magnet in a pile of pins?
When you dip a bar magnet into a pile of pins, the magnetic field of the bar magnet induces magnetism in the pins, causing them to become temporarily magnetized. As a result, the pins are attracted to the magnet and will stick to it. This phenomenon occurs because the magnetic domains within the pins align with the magnetic field of the bar magnet, allowing them to respond to the magnetic force. Once removed from the magnet, most pins will lose their magnetism and return to their non-magnetic state.
What is keeper and its use in magnetism?
A keeper is a iron or a steel bar that is used to retain the strength of magnet.
What is the bar calledt hat is used to keep magnetism while the magnets are being stored?
The bar is called a keeper or a magnetic keeper. It helps to preserve and maintain the strength of the magnet by completing the magnetic circuit and preventing the loss of magnetism.
What is the difference between magnet and magnetic and magnatism?
A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
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.
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.
What type of magnetism is present in a bar magnet?
The known magnetism in a bar magnet is electromagnetism.
How could heating a bar magnet reduce its magnetism?
Heating a bar magnet can cause its magnetic domains to become disordered, reducing its overall magnetic strength. This occurs because the thermal energy disrupts the alignment of the magnetic moments within the material, causing the magnetism to weaken as the domains lose their coherence.
Why is magnetism induced into an iron bar placed near a magnet?
When an iron bar is placed near a magnet, the magnetic field of the magnet aligns the magnetic domains within the iron bar. This alignment increases the overall magnetic field strength of the iron bar, effectively inducing magnetism in the bar.

Why the attraction is zero at the middle of a bar magnet?
Conservation of energy. Attraction is a force, force is zero at conservation of energy.The forces inside the bar magnet configure themselves spatially to conserve energy. The middle of the bar is also an inflection point for energy.
Can magnetism pass through fruit juice?
Magnetism CAN pass through fruit juice. If you were to use a bar magnet on the table attracting another magnet on the other side, it would still attract. Magnetic studs are a good example of magnetism because they can stick/ connect together even through the flap of the ear.

If a magnet bar were heated would it change its magnetic field?
Initially, no. At a certain temperature the bar would suddenly lose its magnetism. This temperature is known as the Curie point of the material. If the magnetism of the bar came from an external source - a solenoid or a permanent magnet - the field would return to its original strength as soon as the bar cooled below the Curie point. If the bar had been itself a permanent magnet almost all the field would stay gone until the bar was re-magnetised by an external field.
What is a rectangle magnet known as?
A rectangle magnet is commonly known as a bar magnet. It has a rectangular shape with a north and south pole at each end, producing a uniform magnetic field around it. Bar magnets are often used in various applications, including compasses, magnetic closures, and educational demonstrations of magnetism.
