Electromagnetism is more useful than regular magnetism because it allows for the manipulation of magnetic fields through the use of electric currents. This enables the creation of stronger and more controllable magnetic fields, making electromagnets versatile and adaptable for various applications such as in motors, generators, and magnetic resonance imaging (MRI) machines.

This enables greater control and versatility in applications such as electric motors, generators, and magnetic resonance imaging (MRI) machines.
Why does passing a current through a wire create a magnet?
That is, basically, the way ALL magnets are created - by moving electric charges. In the case of a permanent magnet, it is mainly the electrons orbiting their atoms that produce this effect. As to the "why", the Special Theory of Relativity provides an answer, but it is fairly complicated. The summary paragraph on Wikipedia (article "Magnetism") says: "As a consequence of Einstein's theory of special relativity, electricity and magnetism are fundamentally interlinked. Both magnetism lacking electricity, and electricity without magnetism, are inconsistent with special relativity, due to such effects as length contraction, time dilation, and the fact that the magnetic force is velocity-dependent. However, when both electricity and magnetism are taken into account, the resulting theory (electromagnetism) is fully consistent with special relativity. ..." The Wikipedia article "Classical electromagnetism and special relativity" provides a more detailed explanation about the relationship between electricity and magnetism, according to the Special Theory of Relativity - but the math is a bit too complicated for my liking.
What is the significance of the electromagnetic field tensor in the study of electromagnetism?
The electromagnetic field tensor is important in electromagnetism because it provides a concise mathematical description of the electromagnetic field. It allows for a more comprehensive understanding of the interactions between electric and magnetic fields, and is essential for formulating the laws of electromagnetism in a unified and consistent manner.
Does steel retain magnetism better than iron?
Yes, steel retains magnetism better than iron because it is an alloy that contains iron along with other elements like carbon. The addition of other elements in steel helps to stabilize and strengthen the magnetic properties, making it more effective at retaining magnetism compared to pure iron.
What are some future applications of Electromagnetism?
Future applications of electromagnetism include developing faster and more efficient magnetic levitation technologies for transportation systems, creating advanced medical imaging techniques using electromagnetic fields, and designing new energy harvesting methods using electromagnetic induction.

Where and when did Michael Faraday invent Electromagnetism?
Michael Faraday did not invent or discover electromagnetism. After Hans Christian Oersted discovered it he simply studied it more.
When can a hovercraft be more useful than a regular vehicle?
Waterlands are a great place to hover about. The Florida Everglades, for example.
Why is a compass rose more useful in the US than in Europe?
Because in the US your probably closer to the magnetic center of the earth, because earth is a magnet and compasses show your direction through magnetism!
How is eletricity and magnetism related?
1.Similar repel , opposite attract:The two opposite kinds of electric charge are called positive and negative. Oppositecharges attract each other , and similar charges repel each other.A magnet has two opposite poles, referred to as north and south. Opposite magneticpoles attract each other, and similar magnetic poles repel each ,exactly as happenswith electric charges.2. The force with which magnetic poles attract or repel each other depends on the strength of the poles and the distance between them. This relationship is similar to Coulomb's inverse square law for electric charges , which iselectric charge= (coulomb constant x first charge x second charge)/(distance)23.Electricity produces magnetic effects and magnetism produces electric effects.The relationship between electricity and magnetism is called electromagnetism.
Treadmill is usefull or not?
Yes, a treadmill is very useful for regular workouts, especially if you prefer exercising at home. It offers a safe and convenient way to walk, jog, or run regardless of the weather. Using a treadmill helps improve heart health, burn calories, and build stamina. When considering one for home use, it's important to compare the treadmill price in Bangladesh to find a model that fits your budget and fitness needs. Many affordable options are available with features like heart rate monitors, incline settings, and foldable designs.
What 4 forces act from a distance?
Gravity, magnetism, and electrostatic.
What type of particle is responsible for magnetism?
Basically, any magnetism is caused by moving electrical charges - that is, by electrical currents.In an electromagnet, a current is made to flow through a conductor. This causes magnetism, but when the current is switched off, there is no more magnetism.In a permanent magnet, the magnetism is caused by the electrons spinning around the atoms. In some materials, like iron, it is possible for atoms to become aligned, in the sense that more will have their axis of rotation point in one direction than in the other. These atoms cause the magnetism, then. In a regular material, every atom is a tiny magnet, but due to the random positions of the individual atoms, these tend to cancel each other on a large scale.
What is the comparative from useful?
The comparative form of "useful" is "more useful."
What is the source of magnetism in materials?
Magnetism, at its root, arises from two sources:Electric currents or more generally, moving electric charges create magnetic fields (see Maxwell's Equations).Many particles have nonzero "intrinsic" (or "spin") magnetic moments. Just as each particle, by its nature, has a certain mass and charge, each has a certain magnetic moment, possibly zero.http://en.wikipedia.org/wiki/Magnetism
