Donahue, Danny. How To Make A Magnetic Field last modified March 24, 2022. https://www.sciencing.com/magnetic-field-4829278/ Linaimages/Shutterstock If you see the expressions 32and 53, you might announce with a flourish that these mean "three squared" and "five cubed," and be able to ...
How do you measure a magnetic field?Principle of Magnetic Resonance Imaging (MRI)The principle behind using MRI for imaging comes from the difference in relaxation time for aligned free hydrogen nuclei to revert to their original state after being exposed to a strong applied field, {eq}B_o {...
How to make a magnetic field stronger. How is the magnetic field oriented around a magnet? How do you increase the magnetic field of a magnet? How to create a static magnetic field. What is an induced magnetic field? How does the magnetic field act like a shield?
To make a magnet repel a metal, one must first understand the properties of a magnet. A magnet has two poles, a north pole and a south pole. When magnets are placed near each other, opposite poles attract and like poles repel one another. When a metal enters a magnetic field, all of...
Magnetic fields with downward curvature are not favourable for prominence formation since the presence of a small quantity of dense material at the summit of a low-beta arcade cannot deform sufficiently the magnetic field lines to remain there in a stable manner. Thus a dip at the field line ...
I want to model this thing in COMSOL that i want to apply a certain magnetic field and see how the shape of the sphere is deformed and by how much ? Does any one has any idea that how can i do that. I have attached a picture of the my model the midd...
To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other ways to align magn...
The magnetic field exists in the region surrounding a bar magnet and is characterized by its strength and direction.
It is electrical current that makes your solenoid work, but if you have enough loops, you can reduce the current. A 10 ohm resistor would make the current be about 1 amp. That is more than enough to get a good magnetic field if you have enough loops(turns) in your solenoid. Yes, a...
