F = mB - mB =0
a bar magnet is placed in a uniform magnetic field B, its poles +m and -m experience force mB and mB along and opposite to the direction of magnetic field B.
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.
A keeper is a iron or a steel bar that is used to retain the strength of magnet.
A dumbbell-shaped magnet is commonly referred to as a "bar magnet." This type of magnet has two distinct poles, a north and a south pole, at each end, resembling the shape of a dumbbell. Bar magnets are often used in experiments and educational demonstrations to illustrate the principles of magnetism.
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.
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.
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.
The known magnetism in a bar magnet is electromagnetism.
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.
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.

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.

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.

As the bar magnet approaches the U magnet, its magnetic field interacts with the magnetic field of the U magnet. If the bar magnet's north pole nears the U magnet's south pole, they will attract each other, leading to a force that pulls the two magnets closer together. Conversely, if the like poles (north-north or south-south) come near each other, they will repel, pushing the bar magnet away from the U magnet. This interaction demonstrates the fundamental principles of magnetism, where opposite poles attract and like poles repel.
