What is the color code given on the two ends of the magnet bar?
The two ends of a magnet bar are typically colored with red and blue to indicate their polarity. Red signifies the north pole, while blue signifies the south pole.
If a bar magnet is cut into two halves the ends nearest the cut prove to have?
opposite poles
What does a electromagnet have that a bar magnet does not have?
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
Is there a scale for magnet strength?
They are bar magnet ,horse shoe magnet ,lime stone magnet.
How will you find out which one is magnet when two identical bars are given one of them is a magnet and the other is a simple iron bar?
One way is to suspend each bar from a string tied around the middle of the bar. The magnetized bar should rotate to orient itself with the Earth north and south magnetic poles. The other bar will just hang there.

WhAT ARE THE ENDS OF THE BAR MAGNET CALLED?
poles
Is the field strength greater closer to the ends of the bar magnet or near the center?
The field strength is greater closer to the ends of the bar magnet than near the center.
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.)
Show bar magnet horse shoe magnet dumb bell magnet etc.?
I'm unable to display images, but I can describe them for you. A bar magnet is a straight magnet with north and south poles at opposite ends. A horseshoe magnet is shaped like a horseshoe, with both poles located at the ends of the curved section. A dumbbell magnet consists of two bar magnets joined at the center. Each magnet has its north pole connected to the south pole of the other magnet, creating a closed loop magnetic field.
You are given a small plotting compass and three grey metal bars one is aluminum one is iron one is magnet how can i identify each one?
The bar that affects the compass is the magnet, The bar that is attracted to the magnet is iron, and the bar that is not attracted to the magnet is aluminum.

opposite poles
What does a electromagnet have that a bar magnet does not have?

What is the proper name for the ends of magnets?
The ends of a bar magnet are generally called the north and south poles. However they are more accurately known as the North Attracting pole and the South Attracting pole as the respective ends of the magnet are drawn to the Earths north and south poles.
Is there a scale for magnet strength?
They are bar magnet ,horse shoe magnet ,lime stone magnet.
What is a pole on a magnet?
The poles of a magnet are the ends of the core of the magnet, where the lines of force emerge. An experiment with iron filings shows the lines of force, by putting a sheet of paper over the magnet and sprinkling fine iron filings. This is an easy thing to do at home. For a bar magnet the poles will be at opposite ends. If you have two such magnets you can experiment and find that like poles repel, opposite poles attract.
Is bar magnet a natural magnet?
no
