"Discover electrons"!!! You mean the Leonhard experiment that sent a ray of electrons through a cathode ray tube and observed the change in the spot of light at the screen? But there WAS no "cancelation", so I'm not sure what you're asking. But there was another experiment that needs to be considered part of the "discovery" of the electron: that of Milikan: the oil-drop experiment. Between the work of Leonhaard (which established the ratio of the electronic mass to the electronic charge) and that of Milikan (which established the charge of the electron) the experimental foundations of the discovery were provided. It ws docuemtned by J. J. Thompson (in "The Electon, early 20th centry") Walter Ludwig Schubert, historyofmatter@hotmail.com

How do you compare magnetic moments of two magnets using deflection magnetometer?

To compare the magnetic moments of two magnets using a deflection magnetometer, you would place one magnet at a known distance from the magnetometer and measure the angle of deflection caused by its magnetic field. Then, you would repeat the process with the second magnet at the same distance and compare the angles of deflection. The magnetic moment of the magnets can be compared by the ratio of the sine of the angles to the distance and the Earth's magnetic field strength.


What does a hall effect sersor do?

As magnets pass a filed they cause a deflection a hall sensor will detect that


Does a electron microscope use magnets?

Yes, an electron microscope uses magnets to focus and direct a beam of electrons onto a specimen. The magnets help to control the path of the electrons and produce high-resolution images.

Atoms become magnets when there?

Atoms become magnets when their electrons are aligned in the same direction, creating a magnetic field. This alignment typically occurs in materials with unpaired electrons and results in a magnetic moment in the atom.


Why aren't all atoms magnets?

Not all atoms are magnets because magnetism is primarily determined by the arrangement of electrons within an atom. In most atoms, the electrons are paired and their magnetic moments cancel each other out, resulting in no net magnetic effect. Only certain atoms with unpaired electrons or aligned spins exhibit magnetic properties.

How are atoms and magnets the same?

Both have an ability to lose or attract electrons.


How does the arrangement of electrons in a magnet compare to metals that are not metallic?

electrons in magnets are organized and generally pointing in the same direction


How can I effectively use magnets for a magnetic board?

To effectively use magnets on a magnetic board, choose strong magnets that can securely hold items in place. Place the magnets strategically to organize and display your items. Experiment with different sizes and shapes of magnets to find what works best for your needs.


Does a TV have a magnet?

Televisions with cathode ray tubes have several strong magnets in them. The magnets are used to aim the electrons that excite the phosphorus on the inside of the CRT. Flat screen TVs do not have magnets in them.
