Which is an electromagnetic device?
a loudspeaker
William Gilbert about how earth is magnet?
That he could do the moon walk.
Will a magnet work on scissors?
They could be if you have magnetic powers
How can you show that iron pieces are attracted by a magnet?
we can show it by experimenting. for eg. iron (which prevents self demagnetisation) also attracts magnets
Can a magnet attract through ceramic tile?
No, but a powerful electromagnet could.
How do you show that a loudspeaker has a magnet inside it?
Ask aba6iii :)!
How could you show that a loud speaker has a magnet in it?
Figure it out yourself
What is the role of a magnet in woofers?
The voice coil of a loudspeaker is placed in an annular space within the magnet assembly and is connected to the loudspeaker's paper cone. An audio signal creates a current in the coil and this generates a magnetic field around the coil which reacts with the permanent magnet of the woofer. The coil and cone move in and out like a piston in a car engine depending on the polarity of the audio signal. This is called the 'Motor effect' and is basically a linear motor.
In Which device is magnetic field present?
1 example is an audio loudspeaker device because a coil and magnet is used to create the sound effect.
What is the part of a loudspeaker that vibrates to make sound?
a speaker uses a voice coil a coil copper wire and a magnet and pole to vibrate a cone
Why might a loudspeaker damage a floppy disc but not a?
A floppy disc use a magnetic pattern to store data, and loudspeakers are usually based around a (strong) magnet. The magnet can upset the magnetic pattern, making the data unreadable.

A dumbbell shaped magnet is called which type of magnet?
How a loudspeaker works?
A loud speaker (like other speakers) produce sound (which is actually vibrations in the air heard by the ear) with a permanent magnet and a temporary magnet in wire form that is wrapped around the permanent magnet. (or a magnet that can be turned on and off by electricity) the speaker translates the sound into a series of electrical currents and then produces the electricity to alter the temporary magnet and making the magnets vibrate and in turn vibrates the air.
Where are the electromagnets in a loudspeaker?
Electromagnets are not used in commercially available loudspeakers due to unlinear sound reproduction, noise induced by the electromagnet current and cost. A permanent magnet with a moving coil in the magnet gap is far superior to an electromagnet considering these three parameters.
Does lgks360 have loudspeaker?
lg ks360 does have a loudspeaker !
How do you disrupt or jam a loudspeaker?
up your neighbour's loudspeaker?
