What energy does an electric fan use?
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
Is a north or south magnet in a compass a permagnet or an electromagnet?

Describe the energy transformation that takes place in a generator?
Mechanical energy to electrical energy. A generator consists of a large magnet placed inside a coil of wire. . When the magnet is rotated (mechanical) it impels the electrons in the wire to move(electrical). Conversely, with suitable electrical engineering, when a magnet is placed inside a wire coil and electricity is passed through the wire, it will make the magnet rotate.
What energy is produced when a coiled wire is spun around a magnet?
Electrical
How is a solenoid similar to a magnet?
A solenoid acts like a magnet when an electrical current is sent through the coil. A permanent magnet is magnetic all the time. Therefore, they are similar when both act like a magnet, but not when the solenoid is turned off.
What do you use in your everyday life which has a magnet?
Fridge,telephone, fan
Does a fan have a magnet?
Not all fans do need a magnet - there are hand fans, punkah walla fans belt driven fans (as in your car) and Stirling engine fans that I can think of that do not need a magnet. It is only electrically driven fans that require a magnet because they work on the principles of electromagnetism.
What energy does an electric fan use?
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
Where is the magnet in a fan?
on the bottom
How do you use an electrical fan safely?
You can use it safely by not puting your hand in the blades when it is turned on.
What form of energy is prodused when electric fan is use?
electrical energy
How do you make a powerful magnet?
To make a powerful magnet, use a strong magnetic material like neodymium. Shape it into a magnet by applying a magnetic field while it cools down. Finally, the magnet can be magnetized by rubbing it against a magnet or by exposing it to an electrical current.
What is true about the magnet if an electric field exists around a magnet?
Then the magnet not only has magnetism, but also an electrical charge.
Why does a telephone use a magnet?
There is a magnet in the both the microphone and speaker. They change differences in air-pressure (in the microphone) to electrical pulses, and in the speaker, they cause the cone to vibrate - creating sound.
Does an electrical convert electrical fan energy into motion?
The electric fan converts electrical energy into mechanical energy used to turn the fan blades, so no.

Are there any magnets in kitchen appliances?
Every electrical spinner contains a magnet, so electric kitchen mixer will also use a magnet.
