Rotate a coil of copper wire between two magnets.
If meiosis did not occur and produce sex cells, organisms would not be able to undergo sexual reproduction. Sexual reproduction is important for genetic diversity and the survival of species. Without meiosis, organisms would reproduce asexually and genetic variation would decrease, potentially leading to detrimental effects on the species' ability to adapt to changing environments.
what would most be likely happen if green plant were exposed to longer days in sunlight
If glycolysis could not happen in a cell, the cell would not produce ATP molecules.
A GeneratorAC and DC generators(also called dynamos). Whenever magnetic flux through a closed wire loop changes current flows in it. We use mechanical energy to produce change in flux and generate electricity.A device that converts mechanical energy into electrical energy is called an Electric Generator. It works by inducing an electric current in a loop of wire by using magnetic fields.An electrical generator or Dynamo. The mechanical energy moves a magnetic field relative to electric coils and creates electricity. Little Dynamos on bicycles provide light at night.
Transcription of the DNA sequence CAT would produce the messenger RNA sequence CAU. This mRNA sequence would then be translated by ribosomes to produce the amino acid histidine.
To create a continuous path for electric current, you need a closed circuit that includes a power source (such as a battery or generator), conductive materials for the current to flow through (such as wires), and a load (such as a light bulb or motor) to utilize the electrical energy. When these components are connected in a loop, the electric current can flow continuously.
Since Electric Motors are not 100%, you could say that they produce "waste". I believe that the majority of that "waste" would be in the form of heat. Part of that heat is lost in the windings and is proportional to the square of the current, and part of it would be friction loss in the bearings. Electric motors are typically better than 90% efficient.
Electric current produce magnetic fields. However, in the case of AC (alternating current, usual in households), the current changes so quickly (and the current has an average value of zero) that I am not sure the effect on a compass would be visible to the naked eye.Electric current produce magnetic fields.

No, an example of an electric current would be using a battery to light a lightbulb.
For the United States of America your keyboard configuration would be "English (United States) - US". I belive the modern configuration is (QWERTY)
They're both true, but I'm not comfortable with the way they're stated. I would have said: -- Electric current through a wire produces magnetic force. -- Moving electrons constitute an electric current, whether or not they're moing througha magnetic field.
The voltage needed to produce a current that can be felt varies from person to person, but typically a voltage above 10 milliamperes can be felt by most individuals. Keep in mind that electrical current can be dangerous, and it is not recommended to intentionally expose oneself to electric shocks.

I will attempt to answer the question I think your asking: 'If an electric generator produces an electric current due to magnetic induction, then why isn't a current produced via the same mechanism in an electric motor?' The answer to the best of my understanding is that it is, or at least, it would be. The reason is that in a generator a conducting wire is rotated in a magnetic field and this induces a current as each charged particle experiences a force as determined by F=q(vxB) [this is the vector form of the equation using the vector product] or F=Bqv if you are unfamiliar with vectors. As this causes electrons to move this manifests itself as an alternating current in a wire. Conversely in a motor and alternating current is passed through a magnetic field in a coil of wire, this time the wire now experiences a force F determined by F=I(lxB). This produces a torque on the centre of the motor and it is this torque that drives the motor. However if you were to rotate the coil of the motor externally without supplying a current to it then the reverse process would take place. This would induce an AC current in the motor which would now function as a generator. As a aside if this current was then driven through the generator it would then rotate exactly as the motor did.
Electric current is both positive and negative. If there were only one of those it would be an open circuit and it would not work. The particles would be able to flow one way but not the other.
Fruits such as lemons and tomatoes, and some vegetables like potatoes, contain positive ions that can attract electrons from metals such as zinc. This effect can be used to produce tiny amounts of electric current in science experiments.
