What is non magnatic alloy material?
A non magnetic alloy material is a bar that cannot attract another component because it has no magnet.
What do the lines around a bar magnet?
magnetic lines of force
On a bar magnet where are lines of magnetic force the greatest?
near both magnetic poles
Do field lines around a current wire look different from those around a bar magnet?
Yes. The field lines of a bar magnet emerge from one end, curve around, and stop at the other end. The field lines around a current-carrying wire are circles, with the wire passing through their centers.
Why are the poles of a bar magnet not situated at the extreme ends of the magnet?
The poles are situated at the ends of the bar magnet. The magnetic lines of force run through the magnet, emerge from one end, fold back around the length of the bar of the magnet, and curl back into the other end. The ends are the magnetic poles, and the magnetic lines of force emerge from one and re-enter the magnet at the other. You can see these lines by laying flat a piece of smooth paper over the magnet and sprinkling iron filings over the paper. Because they are light they will be easily moved into alignment by the magnetic field and will visually show the fields arrangement. (Using a piece of paper makes it easy to tidy up. Without it, the filings will stick to the magnet and be difficult to remove.)
What is the direction of the magnetic field of a bar magnet?
The field lines would leave one pole (end of the magnet) and then curve around one side to come back to the other pole in kind of a semi-oval. Picture two ovals side by side, then picture the bar magnet placed between them, overlaying the long edges of the ovals where the ovals touch. This can be observed by pouring some iron filings onto a piece of paper and then placing a bar magnet underneath the paper. The filings will line up along the field lines providing a visual picture.
Is a bar magnet magnetic?
A bar magnet is a magnet of rectangular shape with a north and and south end, which are sometimes coloured different colours to indicate which end is which.
Do the magnetic lines of force actually exist explain?
Yep they are called lines of flux, I believe. While invisible to the naked eye, like wind, we can see their effects. If you have iron shavings and a bar magnet, place the bar magnet on a piece of paper, then sprinkle the iron shavings all over the paper. The vast majority of them should line up along the lines of flux between the north and south pole of the magnet.
Is there a scale for magnet strength?
They are bar magnet ,horse shoe magnet ,lime stone magnet.
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.
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.
