What else can I help you with?
Do sound waves carry electrical and magnetic energy?
No, sound waves do not carry electrical or magnetic energy. Sound waves are vibrations of particles in a medium, such as air, that propagate as mechanical waves through that medium. They do not involve the movement of electric charges or magnetic fields.
Do waves have magnetic polarity?
No, waves do not have magnetic polarity. Waves are disturbances or vibrations that propagate through a medium or space, and they do not possess magnetic properties. Magnetic polarity is a characteristic of magnetic materials such as magnets, where they have a north and south pole.
Do magnetic fields extend out infinitely?
No, magnetic fields do not extend out infinitely. They have a limited range of influence, determined by the strength of the magnetic source and the medium through which the field is propagating. Beyond a certain distance, the effects of the magnetic field become negligible.
Waves that do not require a medium are?
Electromagnetic waves do not require medium for propagation.
Does every wave has a medium?
No, not all waves require a medium. Electromagnetic waves, such as light and radio waves, can travel through a vacuum because they consist of oscillating electric and magnetic fields. These waves do not require a medium to propagate.
What are the type of ROM?
two types - magnetic in the form of magnetic tape,magnetic disc and optical in the form of compact disc.
What is the main feature of each computer generation?
vacuum tubes, punch cards, magnetic tape, large sizetransistors, punch cards, magnetic tape, harddisc, medium sizeintegrated circuits, punch cards, magnetic tape, harddisk, medium or small sizemicroprocessors, interactive user interface, harddisk, floppy disc, very small size
Is a magnetic disc affected by a theft detection device or magnetic theft alarm sensor?
Yes, a magnetic disc like a hard drive or floppy disk can be affected by a theft detection device or magnetic theft alarm sensor due to the strong magnetic fields they emit. This can potentially cause data loss or corruption on the magnetic disc. It is best to keep such devices away from magnetic fields.
What is a related records stored on a storage medium such as hard disc or optical disc?
a File
What is the Principle of magnetic recording and reproduction explain with sketches?
The principle of magnetic recording and reproduction involves encoding information onto a magnetic medium using changing magnetic fields. When recording, information is stored as magnetic patterns on the medium. To reproduce the information, a magnetic head reads the patterns and converts them into electrical signals for playback. The sketches would show the process of writing and reading magnetic data on a medium using a magnetic head.
Why are there no poles on disc magnets?
Disc magnets do not have poles because they have a symmetrical magnetic field that runs from one flat face to the other. This design allows for a more uniform magnetic field across the entire surface of the disc magnet, making it useful for certain applications such as magnetic levitation or sensor devices.
What storage requires sequential access of data?
magnetic disc
What is rigid magnetic storage medium?
Hard Disk
What is magnetic tape used for?
It is a data storage medium
Is BluRay disc an output device?
A blu ray disc is a storage medium, not an input/output device.
Difference between magnetic tap and magneticdisk?
iron oxide coated very thin film magnetic tape. elastic and flexible sujected to wear and tare modrate life.portable,bulkey with less capaciy. inexpencive. magnetic meterial coated on round shaped polymer disc is magnetic disc.large storage area long life expensive not effected by magnetic field
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.
