How do magnets create a magnetic field? How efficient is a rocket engine? How is a magnetic field produced in an electromagnet? Why was the Van de Graaff generator invented? Hydroelectric power produces electricity using Explain the energy transformation processes in an electromagnet. ...
The most common method of making magnets today involves placing metal in a magnetic field. CRStocker/Shutterstock 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 needl...
What do a wrecking yard, a rock concert and your front door have in common? They each use electromagnets, devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars fr...
The doorbell is a good example of how you can use electromagnets in applications where permanent magnets just wouldn't make any sense. When a guest pushes the button on your front door, the electronic circuitry inside the doorbell closes an electrical loop, meaning the circuit is completed and...
Explore the powerful engineering of electromagnets in this fun and easy electricity project. LearnHow to Make an Electromagnet! Plus, learn why electromagnets are important in our race to reduce our dependence on fossil fuels… They’re the key to electric cars! Electric and hybrid vehicles use ...
In Physics, the law of conservation of energy states thatenergy can neither be created nor be destroyed. This means that in order togenerate electricity, another kind of energy should be used as fuel. Thomas Seebeck (1770-1831): Discovered the “Seebeck Effect“. ...
The total contraption of magnets and conductors make up the generator. Using the wind to turn blades creates the force needed to turn the magnets or the coil of conductor which in turn creates electricity. Below is a step by step process that highlights the methods by which a wind turbine ...
Of course, using a generator to make electricity is just the beginning. After you get your electrons moving along, you'll need an electrical circuit to do anything with it. Find out why next.Electrical Circuits Batteries When you load a battery into an electronic device, you're not simpl...
of salt lessens water's dimagnetic properties. In addition, salt raises the freezing point and lowers the boiling point of water. Salt also strengthens the water's ability to conduct electricity. Due to these effects, magnets do not affect salt water the same way that they do regular water....
