What uses a magnetic field to turn motion to electricity?
A microphone is a good example of a device that utilizes electromagnetic induction (Faraday's Law) to convert motion (vibrations in air) into electricity. The sound vibrates a membrane attached to a little magnet inside a coil of wire. The changing magnetic field induces a current in the wire.
What does an electromagnet do and how does it differ from a regular magnet?
An electromagnet is a type of magnet that uses electricity to create a magnetic field. It can be turned on and off by controlling the flow of electricity. In contrast, a regular magnet is always magnetic and does not require electricity to function.
What is the magnet pull strength of the new magnetic device?
The magnet pull strength of the new magnetic device is 50 pounds.
What can produce electricity to make a magnet?
Electricity can be produced by various methods such as generators, batteries, and solar panels, which can then be used to power a magnet.
Electricity can be used to move magnets which are then used to do work . What device uses electricity in this way?
An electric motor uses electricity to create a magnetic field which interacts with a permanent magnet to produce motion. This motion can be harnessed to do mechanical work in devices like fans, pumps, and vehicles.
Can you magnetize a magnet in order to change it as a permanent magnet by the use of electricity?
No it will only be possible for it to be a temporary one
What is electrical device?
Things that run on or use electricity
Does a magnet just the word magnet conduct electricity?
no it does not.
How are microwaves magnetic?
Inside a microwave oven,microwaves are made when electricity passes through a device called Magnetron.Magnetron uses a strong magnet. The electricity and the magnet make microwave electromagnetic.
Can a magnet be used to produce electricity?
A spinning magnet inside a coil of copper wire will produce electricity.
How do you produce electricity from magnetism?
One way you can produce electricity is by using a U shaped magnet and pushing a metal string in the U shaped magnet!You use a galvanometer attached to the string and when you push it, it will become electrical energy! (A galvanometer measures electricity.)
Is microphone a input or output device?
A microphone is (put simply) a magnet inside a coil of wire. When the noise vibrations hit the magnet it moves creating an electronic field around the wire. That electricity goes into your computer.A microphone is an input device.
How can one use windmills for electricity?
The use of wind power for electricity involves the attachment directly or indirectly of a magnet to the turbine to spin within a dynamo to generate a current.
What does the electro magnet prove about electricity?
An electro magnet proves that Electricity and Magnetism always co-exist in nature
Can connecting a specific amount of magnet to one of your electric wires reduce the electricity usage?
No. Your magnet will fight the electricity.
What uses a magnetic field to turn motion to electricity?
A microphone is a good example of a device that utilizes electromagnetic induction (Faraday's Law) to convert motion (vibrations in air) into electricity. The sound vibrates a membrane attached to a little magnet inside a coil of wire. The changing magnetic field induces a current in the wire.
Is a magnet energy?
A magnet uses the electro-magnetic force. This force also includes electricity. Very basically, it works by electrons exchanging a proton. So a magnet doesn't use energy.
