What are two types of magnet and their shapes?
bar magnet :- cuboid shapecylindrical magnet :- cylinder shape
What comes in varicties called bar horseshoe and electro?
compass
What are different shapes of magnet?
Horseshoe, Bar, U, Ring, Circle, etc.
What is the largest roman numeral number you can make without using a bar?
The largest Roman numeral number that can be made without using a bar is 3,999, which is represented by the letters MMMCMXCIX.
What is 3.5888 repeating decimal using bar notation?
3.58 with the bar only over the 8
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.
What is the moveable bar in a compass called?
The movable bar in a compass is called the compass needle. It is typically a thin magnetized bar that aligns with the Earth's magnetic field to indicate direction.
What happens when a bar magnet is brought near a compass?
gago.
How to find positive on a magnet?
To determine the positive and negative poles on a magnet, you can use a compass. The end of the magnet that attracts the north pole of a compass is the magnet's south pole, and the end that attracts the south pole of a compass is the magnet's north pole. Label these accordingly as positive and negative, or north and south poles.
What happens when you randomly move the bar magnet round about and above the compass one foot or farther?
When you move the bar magnet around and above the compass about one foot away or farther, the compass needle will not be affected by the magnetic field of the bar magnet. The influence of the magnetic field decreases with distance, so at one foot or more away, the compass needle will remain pointing north as it is not close enough to be affected.
Why does a needle of a compass move when you put a bar of metal close to it?
The needle of a compass is a magnet. When a bar of metal is brought close to the compass, it can induce a magnetic field in the needle, causing it to move and align with the magnetic field of the metal bar. This interaction between the magnetic fields of the bar and the compass needle causes the movement.
Why is a small bar magnet able to deflect a compass from Earth's large magnetic field?
The small bar magnet has a stronger magnetic field, at least at short distances.
How can you use a bar magnet and a length of string to make a compass?
Fill the container about half full of water. Float a leaf on the surface of the water, and float the needle on the leaf. That'll be a beautiful demonstration. I think I'll make one, and I thank you for the idea.
How can one determine the poles of the magnetised iron bar?
To determine the poles of a magnetized iron bar, you can use a compass. One end of the bar that attracts the north-seeking end of the compass needle is the north pole of the bar. The opposite end that attracts the south-seeking end of the compass needle is the south pole of the bar.
How do you find north pole in bar magnets?
Use a compass. It will point to a magnet's south pole.
What is a plotting compass?
A plotting compass is a small magnet which is suspended and is free to rotate. When it is near a magnet, the compass will always point in a particular direction (the north pole's direction) becasue of the force of the magnetic field.
How can you magnetise an iton needle permanently using a strong bar magnet?
Rub the iron needle along one direction on the strong bar magnet repeatedly until it becomes magnetized. Make sure to always rub it in the same direction to ensure a consistent magnetic field. This process aligns the magnetic domains within the iron needle, causing it to become permanently magnetized.
