What three ways are magnets and electromagnets alike?
Both magnets and electromagnets have a magnetic field that can attract or repel objects. They can both be used to pick up and manipulate metal objects. Both magnets and electromagnets rely on the alignment of the magnetic domains in their material to generate a magnetic force.
Is a negative object attracting a neutral object considered magnetism?
"Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces.
Hall effect can be used to measure?
Hall effect can be used to measure the strength of a magnetic field. When a current passes through a conductor in a magnetic field, a Hall voltage is generated perpendicular to both the current and the magnetic field. By measuring this Hall voltage, the strength of the magnetic field can be calculated.
Can cooking oil be remove from a mixture using a magnet?
No, cooking oil cannot be removed from a mixture using a magnet. Cooking oil is not magnetic and therefore cannot be attracted or separated by a magnet. Other methods, such as filtration or centrifugation, are typically used to separate oil from a mixture.
In the isolation of aspirin why was vacuum filtration used instead of gravity filtration?
Vacuum filtration was used instead of gravity filtration in the isolation of aspirin to speed up the filtration process by applying negative pressure to draw the solvent through the filter paper more quickly. This helps to separate the solid product from the solvent more efficiently and saves time in the isolation process.
Can liquid be tested by magnetic attraction?
No, liquids cannot be tested by magnetic attraction. Magnetic attraction is typically used to test solid objects containing magnetic materials, such as iron or steel. Liquids do not have magnetic properties that can be detected by a magnet.
What force is used in Maglev trains?
(Electro) magnetism. magnetic attraction and repulsion.
Is filtration used to remove soluble or insoluble substances?
Both..
Which process distillation or filtration is used to produce drinking water from river water?
Both. But filtration is more common.
Which is more effective method of separation- decantation or filtration?
Both decantation and filtration can be effective methods, but they are used for different substances. Decantation is used for solutions that can be separated and filtration is used for solutions with thicker particles that can be filtered out.
The magnetic element used in making metals called?
Iron and Nickel both have magnetic properties.
What is the similarity between a hard disk and a magnetic tape?
Both are magnetic media used to store information.
What do condensation and filtration have in common?
Condensation and filtration are both separation techniques used to separate components of a mixture. Condensation involves converting a gas to a liquid by cooling it, while filtration involves passing a mixture through a filter to separate solid particles from a liquid or gas. Both processes are used in various industries for purification and separation purposes.
What is local local attraction in surveying?
it is a term used to denote any influence, which prevents the needle from pointing to the magnetic north in a given localty
What are a few ways to separate mixtures?
Some ways to separate mixtures include filtration, where a barrier is used to separate solid particles from a liquid, distillation, where liquids are separated based on their boiling points, and magnetism, where a magnet is used to separate magnetic materials from non-magnetic materials.
Which principle is used in a DC motor?
Current carrying conductor kept in a magnetic field gets deflected. This is the basic principle. In short Lorentz force causes the rotation
How is filtration used in everyday lives?
filtration can be used in washing machines and filtering water.
