https://en.wikipedia.org/wiki/Catapult_effect said:In electromagnetics, the catapult effect is a phenomenon occurring when a current is passed through two wires connected by a loose wire in a magnetic field. The loose wire is then catapultedhorizontally away from the magnetic field. This occurs due to the magnetic forces acting in the wires and in the magnetic field itself.
That sounds counter-intuitive... do you have a reference which shows this? Like anorlunda, I'm unfamiliar with this subject.Josielle Abdilla said:And why does a thicker wire increases the catapult effect?
I assumed that, but I'm curious how a larger mass of conductor would incur a greater force... A larger current obviously would but a larger conductor with the same current? Suprising.anorlunda said:I suspect that the real topic is the Lorentz Force
Your first question is quite obvious. Imagine an electromagnet exerting a magnetic field towards the right. This means, that for practical purposes, it has a magnetic field going to the right. Then, we have a magnet also exerting its magnetic field to the right. Both the magnetic fields are "in sync" with each other. There is no motive for either magnetic fields to move at all. They are perfect.Josielle Abdilla said:Hii... can someone explain to me why the electromagnetic wire doesn't experience any motor effect when in parallel to the magnetic field of the permanent magnet? And why does a thicker wire increases the catapult effect?
Ty in advance :)
Magnetism is a force that can attract or repel objects made of certain materials, such as iron, nickel, and cobalt. It is caused by the movement of charged particles, such as electrons, within a substance.
Magnetism works through the interaction between electric currents and the magnetic fields they create. This means that when electrically charged particles move, they create a magnetic field, which can then interact with other magnetic fields to produce attractive or repulsive forces.
The catapult effect is a phenomenon that occurs when a magnet is placed near a metallic object. The magnet creates a magnetic field, which induces a current in the metallic object. This current then creates its own magnetic field, which interacts with the magnet's field to produce a force that can propel the object away from the magnet.
The catapult effect has many practical applications, such as in electric motors, generators, and transformers. It is also used in MRI machines, which use strong magnetic fields to create images of the body's internal structures.
Yes, the catapult effect is an important principle in the production of electricity through electromagnetic induction. This process involves using a magnet and a coil of wire to induce a current, which can then be harnessed to generate electricity. This is the basis for many types of power plants, including hydroelectric, wind, and solar power plants.
