What metals are compass needles made from?
Compass needles are typically made from a ferromagnetic material such as steel. Some compass needles may also contain a small amount of cobalt or nickel to enhance their magnetic properties.
Is shielding effect more noticeable on metals or non-metals?
The shielding effect is more noticeable on metals because they have more loosely held electrons in their outer shells that can effectively shield the inner electrons from the nuclear charge. In contrast, non-metals tend to have stronger attractions between their electrons and nucleus, making the shielding effect less pronounced.
What is the effect on the direction of the compass needle when you close the circuit?
When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.
What will happen if a compass is suspend next to a conductor that is not carrying an electron flow?
If a compass is suspended next to a conductor that is not carrying an electron flow, there will be no effect on the compass. The flow of electrons is what creates a magnetic field, so without electron flow in the conductor, there will be no interaction with the compass needle.
Which are the metals which show and do not show photoelectric effect?
All metals will emit a photoelectric effect. However, alkali metals do so in the visible light spectrum, while other metals do so in near-ultraviolet light.The alkali metals are: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs), and Francium (Fr).
What is the effect of copper and aluminium since they metals?
copper and aluminium are metals since their metals the effect is that their good conductors
Does a cotton ball effect a compass direction?
no
What type of metals make a compass point in different directions?
magnet iron
List the cause and effect connections between the Chinese invation of the Magnetic compass and Zheng He's voyage?
The cause is the Chinese invention of the magnetic compass. The effect is the voyage of Zheng He. The invention of the magnetic compass allowed Zheng He to make his voyage.
What metals are compass needles made from?
Compass needles are typically made from a ferromagnetic material such as steel. Some compass needles may also contain a small amount of cobalt or nickel to enhance their magnetic properties.
What effect will the north pole of a magnet have on a compass when the compass is within the range of the magnet's magnetic field?
It will not have any affect at all HaYLEy
How did the compass effect exploration?
The compass effected exploration because without it, exploration would not have been possible to the early peoples. The compass was invented in China, and some of the earliest explorers were in Egypt. :)
What is the effect of heat energy on alkali metals?
The melting point of alkali metals is low.
Is shielding effect more noticeable on metals or non-metals?
The shielding effect is more noticeable on metals because they have more loosely held electrons in their outer shells that can effectively shield the inner electrons from the nuclear charge. In contrast, non-metals tend to have stronger attractions between their electrons and nucleus, making the shielding effect less pronounced.
Why are the Olympic metals dented?
They did that probably for effect.
What is local attraction and how can we minimize its effect in compass surveying?
Local attraction refers to the effect of nearby magnetic objects on the accuracy of a compass survey. To minimize its impact, you can keep the compass away from metal objects, power lines, or electronic devices, take multiple readings and average them, or use a different type of compass like a gyrocompass which is less susceptible to local attraction.
What do you have to add to a compass to make it in line with the earths magnetic field?
Nothing. That's exactly what a compass does ... as long as it's free to turn, and there are no ferrous metals or other sources of magnetic fields nearby.
