In a permanent magnet motor, electricity is used to create an opposing magnetic field to the one existing due to the magnet. This creates a force that causes the motor to spin.
In a motor without a permanent magnet, electricity is used to create two opposing magnetic fields.
The electric force that makes current flow in a circuit is related to the resistance.
what makes a electric motor get very hot and then shutoff after 20 seconds
Manufacturing is the making of goods. General Electric makes electrical products where Ford makes cars. Toshiba makes electronics such as computers and phones.
an electric current can produce a magnetic field. then,magnetic field within the core of wire will induced the voltage. so magnetic will produce from current at the galvanometer and magnet was far from galvanometer and it induces the voltage
The twist drill uses flutes that act as an Archimedean screw to lift swarf from the hole.
Electricity through a thin wire (filament) makes it glow, which is prevented from burning through the wire by gas inside the bulb.
It is a simple tool. It makes use of simple principle of moment, to lift up water with less effort. By good observation or imagination, human had discovered the principle of moment through work or what ever. Hence there are sayings: - observation is a good teacher - imagination is better than knowledge
An electric circuit is a path in which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. Its so simple, though my friend from extraminds help me with proper answer.
Just do what you feel is right..... your inner conscious knows what is right what is wrong....Be guided by your conscious and not by wants ......... simple......You surely will be a better person.
Stare decisis is the guiding principle for courts that makes decisions predictable and consistent.
It makes calculations with very large and small numbers easier by allowing the 10-factors to be multiplied or divided by adding or subtracting their indices. (The principle of logarithms.)
Diffusion--the perfume molecules diffuse into the atmosphere, which lets you smell the perfume. Opening a bottle of Axe, OTOH, demonstrates the scientific principal of reverse peristalsis because it makes me want to gag every time I smell it.
Reliable, simple and safe. Heat can be regulated by changing the resistance in the circuit.
The common way to do this is with a generator. The basic principle is quite simple: the movement makes wire loops move in a magnetic field; this induces electricity in the wire loops.
Texas Instruments makes the best reviewed scientific calculators.
